                   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 June
    28, 1997, the results of operations for the three- and six-month periods
    ended June 28, 1997, and June 29, 1996, and the cash flows for the
    six-month periods ended June 28, 1997, and June 29, 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.  Acquisition

        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.

        The acquisition has been accounted for using the purchase method of
    accounting, and the results of operations have been included in the
    accompanying financial statements from the date of acquisition. The cost
    of the acquisition exceeded the estimated fair value of the acquired net
    assets by $866,000, which 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 the acquisition
    was 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

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

    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

    Second Quarter 1997 Compared With Second Quarter 1996

        Revenues increased 7% to $18.5 million in the second quarter of 1997
    from $17.3 million in the second quarter of 1996. Revenues increased
    $435,000 due to the acquisition of RCC Industrial Pty. Limited (RCCI) in
    February 1997 (Note 2). Revenues decreased $426,000 due to a stronger
    U.S. dollar relative to currencies in foreign countries in which the
    Company operates. Excluding the impact of the acquisition and foreign
    exchange, revenues from sales of products in the Company's bulk-materials
    line increased approximately $1.0 million, primarily due to increased
    demand in Europe and Canada. Revenues from sales of products in the
    Company's packaged-goods line increased approximately $200,000, primarily
    due to increased demand in the U.S.

        The gross profit margin was unchanged at 41% in the second quarter of
    1997 and 1996.

        Selling, general, and administrative expenses as a percentage of
    revenues were unchanged at 27% in the second quarter of 1997 and 1996.

                               THERMO SENTRON INC.

    Second Quarter 1997 Compared With Second Quarter 1996 (continued)

    Research and development expenses as a percentage of revenues decreased
    slightly to 2.3% in 1997, compared with 2.5% in 1996, primarily due to
    increased revenues.

        Interest income of $497,000 and $493,000 in the second quarter of
    1997 and 1996, respectively, primarily represents interest income earned
    on the invested proceeds from the Company's April 1996 initial public
    offering of common stock. Interest expense decreased to $52,000 in 1997
    from $202,000 in 1996, primarily due to the 1996 repayment of a note
    payable and reduction in short-term borrowings.

        The effective tax rate was 38% in the second quarter of 1997,
    compared with 37% in the second 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.

    First Six Months 1997 Compared With First Six Months 1996

        Revenues increased 7% to $36.5 million in the first six months of
    1997 from $34.0 million in the first six months of 1996. Revenues
    increased $1.4 million due to the acquisition of RCCI in February 1997
    (Note 2) and the solids-flow measurement product line, purchased from
    Endress & Hauser, Inc. in April 1996. Revenues decreased $776,000 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 from sales of products in the Company's
    bulk-materials product line increased approximately $1.1 million,
    primarily due to increased demand in North America and Europe. Revenues
    from sales of products in the Company's packaged-goods product line
    increased approximately $700,000, primarily due to increased demand in
    the U.S.

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

        Selling, general, and administrative expenses as a percentage of
    revenues were unchanged at 27% in the first six months of 1997 and 1996.
    Research and development expenses as a percentage of revenues decreased
    slightly to 2.4% in 1997, compared with 2.9% in 1996, primarily due to
    costs incurred to complete the Company's new electronic control package
    during the first quarter of 1996.

        Interest income of $1,002,000 and $513,000 in the first six months of
    1997 and 1996, respectively, primarily represents interest income earned
    on the invested proceeds from the Company's April 1996 initial public
    offering of common stock. Interest expense decreased to $120,000 in 1997
    from $424,000 in 1996, primarily due to the 1996 repayment of a note
    payable and reduction in short-term borrowings.

        The effective tax rate was 38% in the first six months of 1997 and
    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 June 28, 1997,
    compared with $41.4 million at December 28, 1996. Included in working
    capital are cash, cash equivalents, and available-for-sale investments of
    $34.8 million at both June 28, 1997, and December 28, 1996. During the
    first six months of 1997, operating activities provided $1.2 million of
    cash. The Company used $1.5 million of cash in 1997 to reduce current
    liabilities.

        Excluding available-for-sale investment activity, the Company's
    primary investing activities during the first six months of 1997 included
    an acquisition 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 Engineering Ltd., an
    England-based manufacturer of process-weighing and control equipment, for
    approximately $1.9 million in cash, subject to a post-closing adjustment.
    The Company expended $340,000 for property, plant, and equipment during
    the first six months of 1997 and expects to make capital expenditures of
    approximately $700,000 in the remainder of 1997.

        Certain of the Company's foreign subsidiaries have 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 $9.9 million as of June 28,
    1997.

        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.
