                   Notes to Consolidated Financial Statements


    1.  General

        The interim consolidated financial statements presented have been
    prepared by Thermo Sentron Inc. (the Company) without audit and, in the
    opinion of management, reflect all adjustments of a normal recurring
    nature necessary for a fair statement of the financial position at
    September 27, 1997, the results of operations for the three- and
    nine-month periods ended September 27, 1997, and September 28, 1996, and
    the cash flows for the nine-month periods ended September 27, 1997, and
    September 28, 1996. Interim results are not necessarily indicative of
    results for a full year.

        The consolidated balance sheet presented as of December 28, 1996, has
    been derived from the consolidated financial statements that have been
    audited by the Company's independent public accountants. The consolidated
    financial statements and notes are presented as permitted by Form 10-Q
    and do not contain certain information included in the annual financial
    statements and notes of the Company. The consolidated financial
    statements and notes included herein should be read in conjunction with
    the financial statements and notes included in the Company's Annual
    Report on Form 10-K for the fiscal year ended December 28, 1996, filed
    with the Securities and Exchange Commission.

    2.  Acquisitions

        In February 1997, the Company acquired substantially all of the
    assets of RCC Industrial Electronics Pty. Limited (RCCI) for $1.1 million
    in cash and the assumption of certain liabilities. RCCI is an
    Australian-based manufacturer of in-motion checkweighers for the food and
    pharmaceutical industries and had revenues in 1996 of $1.4 million.

        In July 1997, the Company acquired Westerland Engineering Ltd.
    (Westerland) for $2.0 million in cash. To finance this acquisition, the
    Company borrowed $2.0 million, denominated in British pounds sterling,
    from a bank, pursuant to a promissory note due January 1998 and bearing
    interest at 7 15/16%. Westerland, a manufacturer of process-weighing and
    control equipment, is based in England and had revenues in 1996 of $3.2
    million.

        These acquisitions have been accounted for using the purchase method
    of accounting, and their results of operations have been included in the
    accompanying financial statements from their respective dates of
    acquisition. The excess of the cost of RCCI and Westerland over the
    estimated fair value of the acquired net assets was $866,000 and
    $1,394,000, respectively, and is being amortized over 40 years.
    Allocation of the purchase price was based on an estimate of the fair
    value of the net assets acquired. Pro forma data is not presented since
    these acquisitions were not material to the Company's results of
    operations.

    Item 2 - Management's Discussion and Analysis of Financial Condition and
             Results of Operations

        Forward-looking statements, within the meaning of Section 21E of the
    Securities Exchange Act of 1934, are made throughout this Management's
    Discussion and Analysis of Financial Condition and Results of Operations.
    For this purpose, any statements contained herein that are not statements
    of historical fact may be deemed to be forward-looking statements.
    Without limiting the foregoing, the words "believes," "anticipates,"
    "plans," "expects," "seeks," "estimates," and similar expressions are
    intended to identify forward-looking statements. There are a number of
    important factors that could cause the results of the Company to differ
    materially from those indicated by such forward-looking statements,
    including those detailed under the caption "Forward-looking Statements"
    in Exhibit 13 to the Company's Annual Report on Form 10-K for the fiscal
    year ended December 28, 1996, filed with the Securities and Exchange
    Commission.

    Overview

        The Company designs, develops, manufactures, and sells high-speed
    precision-weighing and inspection equipment for industrial production and
    packaging lines. The Company serves two principal markets: packaged goods
    and bulk materials. The Company's products for the packaged-goods market
    include a broad line of checkweighing equipment and metal detectors that
    can be integrated at various stages in production lines for process
    control and quality assurance. These products are sold to customers in
    the food-processing, pharmaceutical, mail-order, and other diverse
    industries. The Company's bulk-materials product line includes
    conveyor-belt scales, solid-level measurement and conveyor-monitoring
    devices, and sampling systems. These products are sold primarily to
    customers in the mining and materials-processing industries, as well as
    to electric utilities, chemical manufacturers, and other manufacturing
    companies.

        A substantial portion of the Company's sales are derived from sales
    of products outside the United States, through export sales and sales by
    the Company's foreign subsidiaries. Although the Company seeks to charge
    its customers in the same currency as its operating costs, the Company's
    financial performance and competitive position can be affected by
    currency exchange rate fluctuations affecting the relationship between
    the U.S. dollar and foreign currencies. The Company expects an increase
    in the percentage of its revenues derived from international operations
    during the next 12 months. 

    Results of Operations

    Third Quarter 1997 Compared With Third Quarter 1996
 
        Revenues increased 11% to $19.5 million in the third quarter of 1997
    from $17.5 million in the third quarter of 1996. Revenues increased $1.2
    million due to the acquisitions of RCC Industrial Electronics Pty.
    Limited (RCCI) in February 1997 and Westerland Engineering Ltd.
    (Westerland) in July 1997 (Note 2). Revenues decreased $856,000 due to a

    Third Quarter 1997 Compared With Third Quarter 1996 (continued)

    stronger U.S. dollar relative to currencies in foreign countries in which
    the Company operates. Excluding the impact of the acquisitions and
    foreign exchange, revenues increased $1.7 million, primarily due to
    increased bulk-materials product line sales exported from the U.S.,
    resulting from increased demand in Southeast Asia and Latin America.

        The gross profit margin was unchanged at 40% in the third quarter of
    1997 and 1996.

        Selling, general, and administrative expenses as a percentage of
    revenues decreased to 26% in the third quarter of 1997 from 28% in the
    third quarter of 1996, primarily due to increased revenues and, to a
    lesser extent, efforts to control costs. Research and development
    expenses were relatively unchanged in 1997 as compared with 1996.

        Interest income increased to $505,000 in the third quarter of 1997
    from $452,000 in the third quarter of 1996, due to higher average cash
    balances during the period. Interest expense increased to $99,000 in 1997
    from $66,000 in 1996, primarily due to interest incurred on a promissory
    note issued to finance the acquisition of Westerland.

        The effective tax rate was 40% in the third quarter of 1997, compared
    with 38% in the third quarter of 1996. The effective tax rates exceeded
    the statutory federal income tax rate primarily due to the impact of
    state income taxes and foreign tax rate differences. The effective tax
    rate increased in 1997 primarily due to the utilization of certain
    foreign tax loss carryforwards in 1996.

    First Nine Months 1997 Compared With First Nine Months 1996

        Revenues increased 9% to $56.0 million in the first nine months of
    1997 from $51.5 million in the first nine months of 1996. Revenues
    increased $2.6 million due to the acquisitions of RCCI and Westerland in
    1997, and the inclusion of revenues for the full nine-month period from
    the solids-flow measurement product line, purchased from Endress &
    Hauser, Inc. in April 1996. Revenues decreased $1.6 million due to a
    stronger U.S. dollar relative to currencies in foreign countries in which
    the Company operates. Excluding the impact of the acquisitions and
    foreign exchange, revenues increased $3.5 million. Sales of products in
    the bulk-materials product line increased approximately $2.7 million,
    primarily due to increased export sales from the U.S. as discussed in the
    results of operations for the third quarter. To a lesser extent, these
    sales increased due to increased demand in North America. Revenues from
    sales of products in the packaged-goods product line increased
    approximately $800,000, primarily due to increased demand in the U.S.

        The gross profit margin was unchanged at 40% in the first nine months
    of 1997 and 1996.

                               THERMO SENTRON INC.

    First Nine Months 1997 Compared With First Nine Months 1996 (continued)
 
        Selling, general, and administrative expenses as a percentage of
    revenues decreased slightly to 26% in the first nine months of 1997 from
    27% in the first nine months of 1996. Research and development expenses
    decreased to $1.3 million in 1997 from $1.5 million in 1996, primarily
    due to costs incurred to complete the Company's new electronic control
    package during the first quarter of 1996.

        Interest income increased to $1,507,000 in the first nine months of
    1997 from $965,000 in the first nine months of 1996, primarily due to
    increased cash balances for the full nine-month period in 1997 as a
    result of proceeds received from the Company's April 1996 initial public
    offering of common stock. Interest expense decreased to $219,000 in 1997
    from $490,000 in 1996, primarily due to the 1996 repayment of a note
    payable and reduction in short-term borrowings.

        The effective tax rate was 39% in the first nine months of 1997,
    compared with 38% in the first nine months of 1996. The effective tax
    rates exceeded the statutory federal income tax rate primarily due to the
    impact of state income taxes and foreign tax rate differences.

    Liquidity and Capital Resources

        Consolidated working capital was $42.9 million at September 27, 1997,
    compared with $41.4 million at December 28, 1996. Included in working
    capital are cash, cash equivalents, and available-for-sale investments of
    $38.6 million at September 27, 1997, and $34.8 million at December 28,
    1996. During the first nine months of 1997, operating activities provided
    $5.0 million of cash.

        Excluding available-for-sale investments activity, the Company's
    primary investing activities during the first nine months of 1997
    included acquisitions of businesses and purchases of property and
    equipment. In February 1997, the Company acquired substantially all of
    the assets of RCCI for $1.1 million in cash and the assumption of certain
    liabilities (Note 2). In July 1997, the Company acquired Westerland for
    $2.0 million in cash (Note 2). In order to finance the acquisition of
    Westerland, the Company borrowed $2.0 million, denominated in British
    pounds sterling, from a bank, pursuant to a promissory note due January
    1998 and bearing interest at 7 15/16%. The Company expended $484,000 for
    property, plant, and equipment during the first nine months of 1997 and
    expects to make capital expenditures of approximately $250,000 in the
    remainder of 1997.

        Certain of the Company's foreign subsidiaries have foreign-currency-
    denominated line-of-credit arrangements with banks. Notes payable in the
    accompanying 1997 balance sheet includes $3.3 million of short-term
    borrowings under these arrangements. Unused lines of credit were $9.6
    million as of September 27, 1997.

    Liquidity and Capital Resources (continued)

        Although the Company expects to have positive cash flow from its
    existing operations, the Company may require significant amounts of cash
    for the acquisition of complementary businesses. While the Company
    currently has no agreement to make an acquisition, it expects to finance
    any acquisitions through a combination of internal funds, additional debt
    or equity financing from the capital markets, or short-term borrowings
    from Thermedics Inc. or Thermo Electron Corporation, although it has no
    agreement with these companies to ensure that funds will be available on
    acceptable terms or at all. The Company believes that its existing
    resources are sufficient to meet the capital requirements of its existing
    businesses for the foreseeable future.


    PART II - OTHER INFORMATION

    Item 2 - Use of Proceeds

        The Company sold 2,875,000 shares of common stock, par value $.01 per
    share, pursuant to a Registration Statement on Form S-1 (File No.
    333-806), which was declared effective by the Securities and Exchange
    Commission on March 27, 1996. The managing underwriters of the offering
    were NatWest Securities Limited, Lehman Brothers, and Raymond James &
    Associates, Inc. The aggregate gross proceeds of the offering were
    $46,000,000. The Company's total expenses in connection with the offering
    were $3,665,000, of which $2,990,000 was for underwriting discounts and
    commissions and $675,000 was for other expenses paid to persons other
    than directors or officers of the Company, persons owning more than 
    10 percent of any class of equity securities of the Company, or
    affiliates of the Company (collectively, Affiliates). The Company's net
    proceeds from the offering were $42,335,000. As of September 27, 1997,
    the Company had expended $1,145,000 of such net proceeds for the purchase
    of property, plant, and equipment and $2,670,000 for research and
    development. In 1996, the Company used $12,600,000 of the net proceeds to
    repay short-term borrowings, of which $4,600,000 was paid to Thermo
    Electron Corporation, and the balance was paid to persons other than
    Affiliates. In March 1997, the Company used $1,082,000 of the net
    proceeds to acquire the assets of RCC Industrial Electronics Pty. Ltd. As

    interest or dividend bearing instruments. As of September 27, 1997, the
    balance of the net proceeds of $24,838,000 was invested pursuant to a
    repurchase agreement with Thermo Electron Corporation.
