                       ELECTRONIC SENSOR TECHNOLOGY, INC.
                   Notes to Consolidated Financial Statements
                                   (Unaudited)
                                  June 30, 2008

1)   Basis of Presentation

     The accompanying unaudited consolidated financial statements have been
     prepared in accordance with generally accepted accounting principles for
     interim financial statements and with the instructions to Form 10-Q and
     Item 10 of Regulation S-K. Accordingly, they do not include all the
     information and disclosures required for annual financial statements. These
     financial statements should be read in conjunction with the consolidated
     financial statements and related footnotes for the year ended December 31,
     2007, included in the Annual Report filed on Form 10-KSB for the year then
     ended.

     In the opinion of the management of Electronic Sensor Technology, Inc. (the
     "Company"), all adjustments (consisting of normal recurring accruals)
     necessary to present fairly the Company's financial position as of June 30,
     2008, and the results of operations and cash flows for the six month period
     ending June 30, 2008 have been included. The results of operations for the
     six month period ended June 30, 2008 are not necessarily indicative of the
     results to be expected for the full year. For further information, refer to
     the consolidated financial statements and footnotes thereto included in the
     Company's Annual Report filed on Form 10-KSB as filed with the Securities
     and Exchange Commission for the year ended December 31, 2007.

2)   Basis of Consolidation

     The accompanying financial statements include the accounts of the Company
     and its wholly owned subsidiaries. All intercompany balances and
     transactions have been eliminated in consolidation.

3)   Nature of Business and Summary of Significant Accounting Policies

     a)   Nature of Business

          The Company develops and manufactures electronic devices used for
          vapor analysis. It markets its products through distribution channels
          in over 20 countries.

     b)   Cash and Cash Equivalents

          The Company considers highly liquid financial instruments with
          maturities of three months or less at the time of purchase to be cash
          equivalents.

     c)   Certificate of Deposit - Restricted

          The Company's credit card liability is secured and collateralized with
          a certificate of deposit in the amount of approximately $12,000.

     d)   Allowance for Doubtful Accounts

          The allowance for doubtful accounts is based on the Company's
          assessment of the collectibility of customer accounts and the aging of
          the accounts receivable. If there is a deterioration of a major
          customer's credit worthiness or actual defaults are higher than the
          Company's historical experience, the Company's estimates of the
          recoverability of amounts due it could be adversely affected. The
          Company regularly reviews the adequacy of the Company's allowance for
          doubtful accounts through identification of specific receivables where
          it is expected that payments will not be received. The Company also
          establishes an unallocated reserve that is applied to all amounts that
          are not specifically identified. In determining specific receivables
          where collections may not

                                       F-4

          be received, the Company reviews past due receivables and gives
          consideration to prior collection history and changes in the
          customer's overall business condition. The allowance for doubtful
          accounts reflects the Company's best estimate as of the reporting
          dates. Changes may occur in the future, which may require the Company
          to reassess the collectibility of amounts and at which time the
          Company may need to provide additional allowances in excess of that
          currently provided.

     e)   Revenue Recognition

          The Company records revenue from direct sales of products to end-users
          when the products are shipped, collection of the purchase price is
          probable and the Company has no significant further obligations to the
          customer. Costs of remaining insignificant Company obligations, if
          any, are accrued as costs of revenue at the time of revenue
          recognition. Cash payments received in advance of product shipment or
          service revenue are recorded as deferred revenue.

     f)   Shipping and Handling

          The Company accounts for shipping and handling costs as a component of
          "Cost of Sales".

     g)   Inventories

          Inventories are comprised of raw materials, work in process, and
          finished goods. Inventories are stated at the lower of cost or market
          and are determined using the first-in, first-out method.

     h)   Deferred Financing Costs

          Deferred financing costs consist of direct costs incurred by the
          Company in connection with the issuance of its 8% convertible
          debentures. The direct costs include cash payments and fair value of
          warrants issued to the placement agent, which secured the financing.
          Deferred financing costs are amortized over 48 months using the
          effective interest rate method. On March 31, 2008, $3.5 million of the
          $7.0 million 8% convertible debentures was retired and the remaining
          $3.5 million was converted into equity. As such, the unamortized
          deferred financing costs related to the 8% convertible debentures were
          fully amortized at March 31, 2008.

     i)   Property and Equipment

          Property and equipment are stated at cost, net of accumulated
          depreciation. Depreciation is computed using the straight-line method
          over the estimated useful lives of five years.

     j)   Research and Development

          Research and development costs are charged to operations as incurred
          and consists primarily of salaries and related benefits, raw materials
          and supplies.

     k)   Use of Estimates

          The preparation of the financial statements in conformity with
          generally accepted accounting principles requires management to make
          estimates and assumptions that affect the reported amounts of assets
          and liabilities and disclosures of contingent assets and liabilities
          at the date of the financial statements and the recorded amounts of
          revenues and expenses during the reporting period. Actual results
          could differ from those estimates.

     l)   Fair Value of Financial Instruments

          The fair value of certain financial instruments, including accounts
          receivable, accounts payable and accrued liabilities, approximate
          their carrying values due to the short maturity of these

                                        F-5

          instruments. The fair value as of June 30, 2008 of the 9% convertible
          debentures issued by the Company on March 28, 2008 amounts to
          $2,000,000, based on the Company's incremental borrowing rate.

     m)   Long-lived Assets

          The Company reviews long-lived assets, such as property and equipment,
          to be held and used or disposed of, for impairment whenever events or
          changes in circumstances indicate that the carrying amount of an asset
          may not be recoverable. If the sum of the expected cash flows,
          undiscounted and without interest, is less than the carrying amount of
          the asset, an impairment loss is recognized as the amount by which the
          carrying amount of the asset exceeds its fair value. At June 30, 2008
          no assets were impaired.

     n)   Capital Lease

          On June 28, 2007, the Company entered into a capital lease under which
          the present value of the minimum lease payments amounted to $59,200.
          The present value of the minimum lease payments was calculated using a
          discount rate of 11.41%. The principal balance of the capital lease
          obligation amounted to approximately $45,800 at June 30, 2008,
          including approximately $18,900 in the current portion of capital
          lease obligations in the accompanying consolidated balance sheet.

     o)   Derivative Liabilities

          The Company accounts for its liquidated damages pursuant to FASB Staff
          Position No. EITF 00-19-2 "Accounting for Registration Payment
          Arrangements" ("FSP 00-19-2"). FSP 00-19-2 provides that the
          contingent obligation to make future payments or otherwise transfer
          consideration under a registration payment arrangement, should be
          separately recognized and measured in accordance with FASB Statement
          No.5, "Accounting for Contingencies". The registration statement
          payment arrangement should be recognized and measured as a separate
          unit of account from the financial instrument(s) subject to that
          arrangement. If the transfer of consideration under a registration
          payment arrangement is probable and can be reasonably estimated at
          inception, such contingent liability is included in the allocation of
          proceeds from the related financing instrument. The Company had
          registered all shares underlying the 8% convertible debentures as well
          as all shares underlying the warrants related to the 8% convertible
          debentures, but no longer maintains such registration, in light of the
          partial conversion and partial cancellation of the debentures and a
          portion of the warrants.

          The Company accounts for its embedded conversion features and
          freestanding warrants pursuant to SFAS No. 133, "Accounting for
          Derivative Instruments and Hedging Activities", which requires a
          periodic valuation of their fair value and a corresponding recognition
          of liabilities associated with such derivatives. The recognition of
          derivative liabilities related to the issuance of shares of common
          stock is applied first to the proceeds of such issuance, at the date
          of issuance, and the excess of derivative liabilities over the
          proceeds is recognized as other expense in the accompanying
          consolidated financial statements. The recognition of derivative
          liabilities related to the issuance of convertible debt is applied
          first to the proceeds of such issuance as a debt discount, at the date
          of issuance, and the excess of derivative liabilities over the
          proceeds is recognized as other expense in the accompanying
          consolidated financial statements. Any subsequent increase or decrease
          in the fair value of the derivative liabilities, which are measured at
          the balance sheet date, are recognized as other expense or other
          income, respectively.

     p)   Basic and Diluted Earnings Per Share

          Basic earnings per share are calculated by dividing income available
          to stockholders by the weighted-average number of common shares
          outstanding during each period. Diluted earnings per share are
          computed by dividing income available to stockholders, adjusted for
          interest savings on the convertible debenture and changes in income or
          loss associated with the derivative contract

                                        F-6

          that would result if the contract had been recorded as an equity
          instrument for accounting purposes during the period, by the weighted
          average number of common shares outstanding during the period plus the
          net effect of stock options and warrants, effect of the convertible
          debentures, and embedded conversion features.

          The outstanding options, warrants and shares equivalent issuable
          pursuant to embedded conversion features and warrants at June 30, 2008
          are excluded from the loss per share computation for that period due
          to their antidilutive effect.

          The following sets forth the computation of basic and diluted earnings
          per share at June 30:

     q)   Stock Based Compensation

          The Company adopted SFAS No. 123R, "Share Based Payments." SFAS No.
          123R requires companies to expense the value of employee stock options
          and similar awards and applies to all outstanding and vested
          stock-based awards.

          In computing the impact, the fair value of each option is estimated on
          the date of grant based on the Black-Scholes options-pricing model
          utilizing certain assumptions for a risk free interest rate;
          volatility; and expected remaining lives of the awards. The
          assumptions used in calculating the fair value of share-based payment
          awards represent management's best estimates, but these estimates
          involve inherent uncertainties and the application of management
          judgment. As a result, if factors change and the Company uses
          different assumptions, the Company's stock-based compensation expense
          could be materially different in the future. In addition, the Company
          is required to estimate the expected forfeiture rate and only
          recognize expense for those shares expected to vest. In estimating the
          Company's forfeiture rate, the Company analyzed its historical
          forfeiture rate, the remaining lives of unvested options, and the
          amount of vested options as a percentage of total options outstanding.
          If the Company's actual forfeiture rate is materially different from
          its estimate, or if the Company reevaluates the forfeiture rate in the
          future, the stock-based compensation expense could be significantly
          different from what we have recorded in the current period. The impact
          of applying SFAS No. 123R approximated $22,000 in additional
          compensation

                                        F-7

          expense during for the six month period ended June 30, 2008. Such
          amount is included in general and administrative expenses on the
          statement of operations.

     r)   Recently Issued Accounting Pronouncements

          SFAS No. 159

          In February 2007, the FASB issued SFAS No. 159, The Fair Value Option
          for Financial Assets and Financial Liabilities -- including an
          amendment of FAS 115 ("SFAS No. 159"). SFAS No. 159 allows companies
          to choose, at specified election dates, to measure eligible financial
          assets and liabilities at fair value that are not otherwise required
          to be measured at fair value. Unrealized gains and losses shall be
          reported on items for which the fair value option has been elected in
          earnings at each subsequent reporting date. SFAS No. 159 also
          establishes presentation and disclosure requirements. SFAS No. 159 is
          effective for fiscal years beginning after November 15, 2007 and will
          be applied prospectively. The Company is currently evaluating the
          impact of adopting SFAS No. 159 on our consolidated financial
          position, results of operations and cash flows.

          FASB Statement Number 141 (revised 2007)

          In December 2007, the FASB issued FASB Statement No. 141 (revised
          2007), Business Combinations. This Statement replaces FASB Statement
          No. 141, Business Combinations. This Statement retains the fundamental
          requirements in Statement 141 that the acquisition method of
          accounting (which Statement 141 called the purchase method) be used
          for all business combinations and for an acquirer to be identified for
          each business combination. This Statement defines the acquirer as the
          entity that obtains control of one or more businesses in the business
          combination and establishes the acquisition date as the date that the
          acquirer achieves control. This Statement's scope is broader than that
          of Statement 141, which applied only to business combinations in which
          control was obtained by transferring consideration. By applying the
          same method of accounting--the acquisition method--to all transactions
          and other events in which one entity obtains control over one or more
          other businesses, this Statement improves the comparability of the
          information about business combinations provided in financial reports.

          This Statement requires an acquirer to recognize the assets acquired,
          the liabilities assumed, and any noncontrolling interest in the
          acquiree at the acquisition date, measured at their fair values as of
          that date, with limited exceptions specified in the Statement. That
          replaces Statement 141's cost-allocation process, which required the
          cost of an acquisition to be allocated to the individual assets
          acquired and liabilities assumed based on their estimated fair values.

          This Statement applies to all transactions or other events in which an
          entity (the acquirer) obtains control of one or more businesses (the
          acquirer), including those sometimes referred to as "true mergers" or
          "mergers of equals" and combinations achieved without the transfer of
          consideration, for example, by contract alone or through the lapse of
          minority veto rights. This Statement applies to all business entities,
          including mutual entities that previously used the
          pooling-of-interests method of accounting for some business
          combinations. It does not apply to: (a) The formation of a joint
          venture, (b) The acquisition of an asset or a group of assets that
          does not constitute a business, (c) A combination between entities or
          businesses under common control, (d) A combination between
          not-for-profit organizations or the acquisition of a for-profit
          business by a not-for-profit organization.

          This Statement applies prospectively to business combinations for
          which the acquisition date is on or after the beginning of the first
          annual reporting period beginning on or after December 15, 2008. An
          entity may not apply it before that date. Management believes this
          Statement will have no impact on the financial statements of the
          Company once adopted.

                                        F-8

          FASB Statement Number 160

          In December 2007, the FASB issued FASB Statement No. 160 -
          Noncontrolling Interests in Consolidated Financial Statements - an
          amendment of ARB No. 51. This Statement applies to all entities that
          prepare consolidated financial statements, except not-for-profit
          organizations, but will affect only those entities that have an
          outstanding noncontrolling interest in one or more subsidiaries or
          that deconsolidate a subsidiary. Not-for-profit organizations should
          continue to apply the guidance in Accounting Research Bulletin No. 51,
          Consolidated Financial Statements, before the amendments made by this
          Statement, and any other applicable standards, until the Board issues
          interpretative guidance.

          This Statement amends ARB 51 to establish accounting and reporting
          standards for the noncontrolling interest in a subsidiary and for the
          deconsolidation of a subsidiary. It clarifies that a noncontrolling
          interest in a subsidiary is an ownership interest in the consolidated
          entity that should be reported as equity in the consolidated financial
          statements. Before this Statement was issued, limited guidance existed
          for reporting noncontrolling interests. As a result, considerable
          diversity in practice existed. So-called minority interests were
          reported in the consolidated statement of financial position as
          liabilities or in the mezzanine section between liabilities and
          equity. This Statement improves comparability by eliminating that
          diversity.

          A noncontrolling interest, sometimes called a minority interest, is
          the portion of equity in a subsidiary not attributable, directly or
          indirectly, to a parent. The objective of this Statement is to improve
          the relevance, comparability, and transparency of the financial
          information that a reporting entity provides in its consolidated
          financial statements by establishing accounting and reporting
          standards that require: (a) The ownership interests in subsidiaries
          held by parties other than the parent be clearly identified, labeled,
          and presented in the consolidated statement of financial position
          within equity, but separate from the parent's equity, (b) The amount
          of consolidated net income attributable to the parent and to the
          noncontrolling interest be clearly identified and presented on the
          face of the consolidated statement of income, (c) Changes in a
          parent's ownership interest while the parent retains its controlling
          financial interest in its subsidiary be accounted for consistently. A
          parent's ownership interest in a subsidiary changes if the parent
          purchases additional ownership interests in its subsidiary or if the
          parent sells some of its ownership interests in its subsidiary. It
          also changes if the subsidiary reacquires some of its ownership
          interests or the subsidiary issues additional ownership interests. All
          of those transactions are economically similar, and this Statement
          requires that they be accounted for similarly, as equity transactions,
          (d) When a subsidiary is deconsolidated, any retained noncontrolling
          equity investment in the former subsidiary be initially measured at
          fair value. The gain or loss on the deconsolidation of the subsidiary
          is measured using the fair value of any noncontrolling equity
          investment rather than the carrying amount of that retained
          investment, (e) Entities provide sufficient disclosures that clearly
          identify and distinguish between the interests of the parent and the
          interests of the noncontrolling owners.

          This Statement is effective for fiscal years, and interim periods
          within those fiscal years, beginning on or after December 15, 2008
          (that is, January 1, 2009, for entities with calendar year-ends).
          Earlier adoption is prohibited. This Statement shall be applied
          prospectively as of the beginning of the fiscal year in which this
          Statement is initially applied, except for the presentation and
          disclosure requirements. The presentation and disclosure requirements
          shall be applied retrospectively for all periods presented. Management
          believes this Statement will have no impact on the financial
          statements of the Company once adopted.

          FASB 161 - Disclosures about Derivative Instruments and Hedging
          Activities

          In March 2008, the FASB issued FASB Statement No. 161, which amends
          and expands the disclosure requirements of FASB Statement No. 133 with
          the intent to provide users of financial statements with an enhanced
          understanding of; how and why an entity uses derivative instruments,
          how the derivative instruments and the related hedged items are
          accounted for and how the related

                                        F-9

          hedged items affect an entity's financial position, performance and
          cash flows. This Statement is effective for financial statements for
          fiscal years and interim periods beginning after November 15, 2008.
          Management believes this Statement will have no impact on the
          financial statements of the Company once adopted.

          FASB 161 - The Hierarchy of Generally Accepted Accounting Principles

          In May 2008, the Financial Accounting Standards Board (FASB) issued
          Statement of Financial Accounting Standards (SFAS) No. 162, "The
          Hierarchy of Generally Accepted Accounting Principles." The new
          standard is intended to improve financial reporting by identifying a
          consistent framework, or hierarchy, for selecting accounting
          principles to be used in preparing financial statements that are
          presented in conformity with U.S. generally accepted accounting
          principles (GAAP) for non-governmental entities. We are currently
          evaluating the effects, if any, that SFAS No. 162 may have on our
          financial reporting.

4)   Convertible debentures

     8% Convertible Debentures

     During December 2005, we issued in a private offering, $7,000,000 aggregate
     principal amount of 8% convertible debentures due December 7, 2009. The
     convertible debentures were convertible at any time on or prior to the
     maturity date at the option of the debenture holder at a conversion price
     of $0.4544, which was subsequently reduced to $0.4000 as per a Forbearance
     and Amendment Agreement, dated September 7, 2006, with the holders of the
     convertible debentures and can be redeemed at the lesser of $0.4000 or 90%
     of the average of the volume weighted average price for the 20 consecutive
     trading days immediately prior to the conversion date. Interest on the
     convertible debentures was payable in cash or stock, at the Company's
     option.

     In connection with the issuance of the convertible debentures, the Company
     issued five-year warrants to purchase 12,130,314 shares of common stock at
     an exercise price of $0.4761 per share, which was subsequently reduced to
     $0.4300 per share as per a Forbearance and Amendment Agreement, dated
     September 7, 2006, with the holders of the warrants.

     We paid professional fees of approximately $592,000 and issued 485,213
     warrants with a fair value of approximately $136,000 relating to the
     issuance of the convertible debentures and warrants. The payments of
     professional fees and the fair value of the warrants, aggregating
     approximately $729,000, were recorded as deferred financing costs.

     A Conversion and Termination Agreement was entered into with the debentures
     holders on February 26, 2008. Pursuant to the agreement, the convertible
     debentures holders agreed that in exchange for $3,500,000, the debenture
     holders would convert $3,500,000 of the principal amount of their 8%
     convertible debentures, together with accrued interest thereon, at a
     conversion price of $0.35 per share of Common Stock. Upon receipt of the
     foregoing sum and the conversion shares of Common Stock, the debenture
     holders agreed to cancel the remainder of their 8% convertible debentures
     and 50% of the shares of Common Stock underlying warrants. With respect to
     the remaining 6,065,157 shares of Common Stock underlying the warrants,
     they will otherwise continue in full force and effect in accordance with
     their terms. On March 31, 2008, we remitted $3,500,000 in cash and
     transferred 10,400,000 shares of common stock to the debenture holders to
     completely retire the 8% convertible debentures.

     The extinguishment of the convertible debentures resulted in a gain of
     approximately $1,261,900, which included the write off of related
     unamortized deferred financing costs of approximately $302,600.

                                        F-10

     9% Convertible Debentures

     On March 28, 2008, we received $5,500,000 from an investor, $3,500,000 of
     which was for Common Stock of the Company, and $2,000,000 for a convertible
     debenture bearing an interest rate of 9%, payable semi-annually in cash.
     The common stock shares were issued at a price of $0.0405 per share. The 9%
     convertible debenture has a five (5)-year term, and the conversion rate of
     the debenture is $0.0486. The difference between the conversion rate of the
     debenture and the closing price of the Company's common stock on the date
     of issuance resulted in a note discount of approximately $58,000. The note
     discount will be amortized over the term of the convertible debenture.

     A condition of the new investment required the Company to use $3,500,000 to
     extinguish the 8% convertible debentures and this event occurred on March
     31, 2008.

5)   Derivative Liabilities

     In connection with the issuance of the 8% convertible debentures in
     December 2005, the Company determined that the conversion feature of the
     convertible debentures represents an embedded derivative since the
     debentures are convertible into a variable number of shares upon
     conversion. Because there is no explicit number of shares that are to be
     delivered upon satisfaction of the convertible debentures and that there is
     no cap on the number of shares to be delivered upon expiration of the
     contract to a fixed number, the Company is unable to assert that it had
     sufficient authorized and unissued shares to settle its obligations under
     the convertible debentures and therefore, net-share settlement is not
     within the control of the Company. Accordingly, the convertible debentures
     are not considered to be conventional debt under EITF 00-19 and the
     embedded conversion feature must be bifurcated from the debt host and
     accounted for as a derivative liability.

     A Conversion and Termination Agreement was entered into with the 8%
     convertible debenture holders on February 26, 2008. Pursuant to the
     agreement, the convertible debenture holders agreed that in exchange for
     $3,500,000, the debenture holders would convert $3,500,000 of the principal
     amount of their 8% convertible debentures, together with accrued interest
     thereon, at a conversion price of $0.35 per share of Common Stock. Upon
     receipt of the foregoing sum and the conversion shares of Common Stock, the
     debenture holders agreed to cancel the remainder of their 8% convertible
     debentures and 50% of the shares of Common Stock underlying warrants. With
     respect to the remaining shares of Common Stock underlying the warrants,
     they will otherwise continue in full force and effect in accordance with
     their terms. On March 31, 2008, we remitted $3,500,000 in cash and
     transferred 10,400,000 shares of Common Stock to the debenture holders.

     As a result of the satisfaction of the Company's obligations under its 8%
     convertible debentures, the Company reclassified the derivative liabilities
     balance outstanding at March 31, 2008 from liability to equity. The amount
     of derivative liabilities that was reclassified to equity approximated
     $2,053,000.

6)   Stockholders' Equity

     Options

     In 2005, the Board of Directors adopted the Electronic Sensor Technology,
     Inc. 2005 Stock Incentive Plan. The purpose of the Stock Incentive Plan is
     to attract and retain the services of experienced and knowledgeable
     individuals to serve as our employees, consultants and directors. On the
     date the Stock Incentive Plan was adopted, the total number of shares of
     common stock subject to it was 5,000,000. The Stock Incentive Plan is
     currently administered by the Board of Directors, and may be administered
     by any Committee authorized by the Board of Directors, so long as any such
     Committee is made up of Non-Employee Directors, as that term is defined in
     Rule 16(b)-3(b) of the Securities Exchange Act of 1934.

     The Stock Incentive Plan is divided into two separate equity programs: the
     Discretionary Option Grant Program and the Stock Issuance Program. Under
     the Discretionary Option Grant Program, eligible persons

                                        F-11

     may, at the discretion of the administrator, be granted options to purchase
     shares of common stock and stock appreciation rights. Under the Stock
     Issuance Program, eligible persons may, at the discretion of the
     administrator, be issued shares of common stock directly, either through
     the immediate purchase of such shares or as a bonus for services rendered
     for Electronic Sensor Technology (or a parent or subsidiary of Electronic
     Sensor Technology).

     Pursuant to the terms of the Discretionary Option Grant Program, the
     exercise price per share is fixed by the administrator, but may not be less
     than 85% of the fair market value of the common stock on the date of grant,
     unless the recipient of a grant owns 10% or more of Electronic Sensor
     Technology's common stock, in which case the exercise price of the option
     must not be less than 110% of the fair market value. An option grant may be
     subject to vesting conditions. Options may be exercised in cash, with
     shares of the common stock of Electronic Sensor Technology already owned by
     the person or through a special sale and remittance procedure, provided
     that all applicable laws relating to the regulation and sale of securities
     have been complied with. This special sale and remittance procedure
     involves the optionee concurrently providing irrevocable written
     instructions to: (i) a designated brokerage firm to effect the immediate
     sale of the purchased shares and remit to Electronic Sensor Technology, out
     of the sale proceeds available on the settlement date, sufficient funds to
     cover the aggregate exercise price payable for the purchased shares plus
     all applicable federal, state and local income and employment taxes
     required to be withheld by Electronic Sensor Technology by reason of such
     exercise and (ii) Electronic Sensor Technology to deliver the certificates
     for the purchased shares directly to such brokerage firm in order to
     complete the sale. The term of an option granted pursuant to the
     Discretionary Option Grant Program may not be more than 10 years.

     The Discretionary Option Grant Program also allows for the granting of
     Incentive Options to purchase common stock, which may only be granted to
     employees, and are subject to certain dollar limitations. Any options
     granted under the Discretionary Option Grant Program that are not Incentive
     Options are considered Non-Statutory Options and are governed by the
     aforementioned terms. The exercise price of an Incentive Option must be no
     less than 100% of the fair market value of the common stock on the date of
     grant, unless the recipient of an award owns 10% or more of Electronic
     Sensor Technology's common stock, in which case the exercise price of an
     incentive stock option must not be less than 110% of the fair market value.
     The term of an Incentive Option granted may not be more than five years if
     the option is granted to a recipient who owns 10% or more of Electronic
     Sensor Technology's common stock, or 10 years for all other recipients of
     Incentive Options. Incentive Options are otherwise governed by the general
     terms of the Discretionary Option Grant Program.

     Pursuant to the terms of the Stock Issuance Program, the purchase price per
     share of common stock issued is fixed by the administrator, but may not be
     less than 85% of the fair market value of the common stock on the issuance
     date, unless the recipient of a such common stock owns 10% or more of
     Electronic Sensor Technology's common stock, in which case the purchase
     price must not be less than 100% of the fair market value. Common stock may
     be issued in exchange for cash or past services rendered to Electronic
     Sensor Technology (or any parent or subsidiary of Electronic Sensor
     Technology). Common stock issued may be fully and immediately vested upon
     issuance or may vest in one or more installments, at the discretion of the
     administrator.

     Management used Black Scholes methodology to determine the fair value of
     the options on the date of issue based on the following assumptions. The
     expected volatility was based on the average historical volatility of

     The fair value of the granted stock options shares was approximately
     $237,000 or $0.09 per share. Approximately $114,000 and $22,000 were
     charged to compensation expense in 2007 and in the six month period ended
     June 30, 2008, respectively. The remaining amount will be amortized to
     compensation expense over future periods based on the vesting schedule of
     the respective stock option shares. The total compensation cost related to
     nonvested awards not yet recognized amounted to approximately $90,000 at
     June 30, 2008. This compensation cost will be recognized over the weighted
     average period of the remaining terms of the stock options, unless the
     options are terminated sooner.

Item 2.  Management's Discussion and Analysis or Plan of Operation.

You should read the following discussion and analysis of our financial condition
and results of operations together with our interim financial statements and the
related notes appearing at the beginning of this report. The interim financial
statements and this Management's Discussion and Analysis of Financial Condition
and Results of Operations should be read in conjunction with the financial
statements and notes thereto for the year ended December 31, 2007 and the

of Operations, both of which are contained in our Annual Report on Form 10-KSB
filed with the Securities and Exchange Commission.

--------------------------------------------------------------------------------

Overview

The Company is engaged in the development, manufacturing, and sales of a
patented product called zNose(R); a device designed to detect and analyze
chemical odors and vapors, or, in other words, an electronic "nose." We believe
the zNose(R) is superior to other electronic "noses" because of its speed,
specificity and sensitivity. The zNose(R) is capable of measuring and
quantifying the chemistry of any compound, fragrance, vapor or odor with parts
per trillion sensitivity in 10 seconds. We also believe the zNose(R) has the
unique ability to quantify and speciate the subject chemical vapor by creating
visual olfactory images. This enables the measured odor or vapor to be easily
identified by the user.

We believe that our products will have broad applications in the homeland
security, analytical instrumentation/quality control, and environmental
monitoring and detection markets. The Company is involved in ongoing product
research and development efforts in that regard. The Company has also
concentrated its efforts on further product development, testing and proving and
continuing to expand our sales and support organization.

The Company was originally incorporated under the laws of the state of Nevada as
"Bluestone Ventures, Inc." on July 12, 2000. From inception until February 1,
2005, we engaged in the business of acquiring, exploring and developing certain
mining properties in Ontario, Canada. Upon acquisition of Electronic Sensor
Technology, L.P. ("ELP"), we abandoned our mining business and adopted ELP's
business of developing, manufacturing and selling the vapor analysis device. On
January 26, 2005, we changed our name to "Electronic Sensor Technology, Inc."

Our executive offices are located at 1077 Business Center Circle, Newbury Park,
California 91320 and our telephone number is (805) 480-1994.

Critical Accounting Policies

The Company records revenue from direct sales of products to end-users when the
products are shipped, collection of the purchase price is probable and the
Company has no significant further obligations to the customer. Costs of
remaining insignificant Company obligations, if any, are accrued as costs of
revenue at the time of revenue recognition. Cash payments received in advance of
product shipment or service revenue are recorded as deferred revenue.

The preparation of the financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosures of contingent assets and liabilities at the date of the financial
statements and the recorded amounts of revenues and expenses during the
reporting period. Actual results could differ from those estimates.

The Company reviews long-lived assets, such as property and equipment, to be
held and used or disposed of, for impairment whenever events or changes in
circumstances indicate that the carrying amount of an asset may not be
recoverable. If the sum of the expected cash flows, undiscounted and without
interest, is less than the carrying amount of the asset, an impairment loss is
recognized as the amount by which the carrying amount of the asset exceeds its
fair value. At June 30, 2008 no assets were impaired.

                                       2

Plan of Operations

Over the course of the next 12 months, we intend to execute our business plan
and focus our business development efforts in the following key areas:

     o    By diversifying our product offerings to enhance the usefulness of our
          solutions for customers who will have already adopted one or more
          products;

     o    By enhancing our product lines and developing new products to attract
          new customers; and

     o    By developing partnering relationships with wide-ranging sales and
          distribution channel leaders already serving our vertical market space
          in a way that assists them in developing new revenue streams and
          opportunities through improved technical and sales support and
          customer services.

Six Months Ended June 30, 2008 Compared to Six Months Ended June 30, 2007

Revenues are derived from product sales and product support services. For the
six months ending June 30, 2008, revenues were $760,000 which was $408,000 less
than for the same period in 2007. For the quarter, revenues were $325,000 below
second quarter 2007. The decreases in revenues resulted from 9 and 15 fewer
instruments shipped in the quarter and year to date, respectively. Performance
continues to be severely impacted by a significant drop in business from our
Chinese distributor whose year-to-date purchases are 70% below that of last
year. The combined revenues from all other geographical markets, excluding
China, are approximately even with last year with growth in the domestic market,
offsetting a decrease in the European market.

Cost of Sales consist of product costs and expenses associated with product
support services. For the three and six month periods ending June 30, 2008, cost
of sales were $233,000 and $461,000, compared to $331,000 and $585,000 in 2007.
For the same periods, cost of sales, as a percentage of revenues, were 64% and
61%, respectively, versus 48% and 50%, in 2007. Cost of sales continues to be
negatively impacted by overhead spending and labor variances totaling $69,000
for the six month period, compared to $9,000 in 2007. The variances were caused
by a slow down in production to reflect lower sales activities and to work-off
on-hand inventory. Excluding the impact of the variances, cost of sales for the
first six months of 2008 would be 52% of revenues or 3% worse than last year.

Gross profit was $299,000 or 39% of sales for the six months ending June 30,
2008, compared to $583,000 or 50% of sales for the same period in 2007. The
decrease in gross margin over last year is attributed to lower sales volume and
to the labor and overhead variances written off to cost of sales as noted above.
Excluding the impact of the variances, gross margin is 3% worse than last year
due to an unfavorable sales mix for ancillary items for our products.

                                       3

Research and Development costs for the six months ending June 30, 2008 were
$349,000 versus $411,000 for the same period in 2007. The $62,000 improvement is
attributed to lower personnel expenses due to reduction of census ($51,000), and
to non-recurring patent attorney expenses incurred in 2007.

Selling, General and Administrative expenses for the six months ending June 30,
2008 were $1,141,000, compared to $1,387,000 for the same period in 2007. The
$246,000 decrease resulted from a reduction of personnel expenses due to
reduction of census ($142,000), net reduction of outside services ($30,000),
reduction of operating expenses ($53,000), and net difference between severance
amounts paid in 2007 ($116,000) and in 2008 ($82,000), offset by an increase in
promotional expenses ($13,000).

Interest expense for the six months ending June 30, 2008 was $786,000, as
compared to $1,429,000 for the same period in 2007. The $643,000 reduction in
interest expense is due to retirement of the $7.0 million 8% convertible
debentures, and related debt discount, on March 31, 2008. Previously, interest
expense included both interest accrued on the 8% convertible debentures as well
as amortization of the related debt discount. During the second quarter,
interest expense pertains mostly to the interest accrued on the $2.0 million
convertible debenture, which was issued on March 28, 2008.

Other income-derivatives primarily consist of the decrease in the fair value of
derivative liabilities between the measurement dates which are the balance sheet
dates. On March 31, 2008, we satisfied our obligations under the 8% convertible
debentures and as a result, the Company can assert that it has a sufficient
amount of authorized and unissued shares to settle its obligations which can be
settled in shares. Accordingly, the Company reclassified all contracts,
warrants, and other convertible instruments outstanding at March 31, 2008 from
liability to equity (see Note 5).

Gain on extinguishment of debt is the gain realized from the early retirement of
the 8% convertible debentures on March 31, 2008 (see Note 4).

Liquidity and Capital Resources

For the six months ending June 30, net cash used by the Company for operating
activities were $900,112 and $901,286 for 2008 and 2007 respectively. Cash used
for the six months ending June 30, 2008 was comprised of the net loss for the
period of $392,036, less net non-cash items (including depreciation and
amortization expenses of $24,167, issuance of common shares for payment of
interest of $280,000, amortization of debt discount of $586,269, amortization of
deferred financing costs of $45,387, stock based compensation of $21,931, less
decrease in fair value of derivative liability of $323,210, gain on early
retirement of debt of $1,261,864) of $627,320 plus the net change in operating
assets and liabilities of $119,244. Cash used in operations during the same six
months of 2007 was comprised of the net loss for the period of $2,183,841, plus
net non-cash expenses (including depreciation and amortization expenses of
$26,184, stock based compensation of $72,357, amortization of debt discount of
$1,166,667, amortization of deferred financing costs of $90,774, less decrease
in fair value of derivative liability of $450,293, decrease in allowance for
doubtful accounts of $4,784) of $900,905, and plus the net change in operating
assets and liabilities of $381,650.

Investing activities provided cash of $7,495 in the first six months of 2008 and
used cash of $84,675 during the same period in 2007. For the period, cash of
$9,884 was provided from the sale of property and equipment and $2,389 was used
to purchase capital equipment. In 2007, there was an increase in our certificate
of deposit of $21,000 and $63,675 was used to purchase capital equipment.

Financing activities for the first six months of 2008 provided cash of
$1,991,316 which included $2,000,000 received from the issuance of 9%
convertible debentures to an investor, $3,500,000 from the issuance of equity to
the same investor, less $3,500,000 used to retire the 8% convertible debentures
and a decrease in capital lease obligation of $8,684. There were no financing
activities for the first six months of 2007.

On June 30, 2008 the Company's cash (including cash equivalents) was $1,347,300,
compared to $108,200 on June 30, 2007. The Company had a working capital on June
30, 2008 of $1,840,300. The Company's working deficit at June 30, 2007 was
$2,606,000 - excluding derivative liabilities; working capital would be
$300,200.

Seasonality and Quarterly Results

We have not experienced and do not foresee any seasonality to our revenues or
our results of operations.

Inflation

Although we currently use a limited number of sources for most of the supplies
and services that we use in the manufacturing of our vapor detection and
analysis technology, our raw materials and finished products are sourced from
cost-competitive industries. While prices for our raw materials may vary
significantly based on market trends, we have not experienced and do not foresee
any material inflationary trends for our product sources.

Off-Balance Sheet Arrangements

We do not have any off-balance sheet arrangements.

Item 3.  Quantitative and Qualitative Disclosures About Market Risk.

This Item is not applicable to smaller reporting companies.

Item 4T. Controls and Procedures.

The company's Chief Executive Officer and Chief Financial Officer, after
evaluating the effectiveness of the company's disclosure controls and procedures
(as defined in Rules 13a-15(e) under the Securities Exchange Act of 1934, as
amended) as of the end of the period covered by this quarterly report on Form
10-Q, have concluded that, based on such evaluation, the company's disclosure
controls and procedures were effective to ensure that material information
relating to the company is recorded, processed, summarized, and reported in a
timely matter. In designing and evaluating the disclosure controls and
procedures, the company's management recognized that any controls and
procedures, no matter how well designed and operated, can provide only
reasonable assurance of achieving the desired control objectives, and the
company's management necessarily was required to apply its judgment in
evaluating the cost-benefit relationship of possible controls and procedures.

There were no changes in the company's internal control over financial reporting
that occurred during the period covered by this quarterly report that have
materially affected, or are reasonably likely to materially affect, the
company's internal control over financial reporting.
