          PLEDGE AGREEMENT,  dated as of July 6, 1998, by and between Stanley S.
Binder (the "Executive") and Barringer Technologies Inc. (the "Company").

                              W I T N E S S E T H:

          WHEREAS,  the Company has loaned to the Executive the sum of $500,000;
such loan being evidenced by a non-recourse secured promissory note (the "Note")
in the  principal  amount  of  $500,000  made by the  Executive  in favor of the
Company; and

          WHEREAS, the loan to the Executive is to be secured by a pledge by the
Executive to the Company of 49,000 shares of common  stock,  $0.01 par value per
share,  of the  Company  owned by the  Executive  and the other  Collateral  (as
defined below) referenced herein; and

          WHEREAS,  the parties  hereto  desire to set forth the terms of and to
evidence  the  Executive's  grant to the  Company of a security  interest in the
Collateral.

          NOW,  THEREFORE,  in  consideration  of the  mutual  covenants  herein
contained,  and for other  good and  valuable  consideration,  the  receipt  and
sufficiency of which is hereby  acknowledged,  the Executive  hereby agrees with
the Company as follows:

          Section  1.  Definitions.  The  following  terms,  when  used  in this
Agreement,  shall have the following  meanings  (such  definitions to be equally
applicable to the singular and plural forms thereof):

          "Default"  means the  failure to make any payment of  principal  of or
interest  on, or any other  amounts  due  under,  the Note when due,  whether at
maturity, upon acceleration or otherwise.

          "Distributions"  means all  stock  dividends,  liquidating  dividends,
shares  of stock  resulting  from  stock  splits,  reclassifications,  warrants,
options,  non-cash  dividends and other  distributions on or with respect to the
Shares,  whether  similar or dissimilar to the foregoing,  but shall not include
Dividends.

          "Dividends"  means  regular  dividends  declared  with  respect to the
Shares.

          "Liabilities" means the Note, and all amounts becoming due thereunder,
and all other payment  obligations  of the Executive  hereunder or thereunder or
any instrument executed pursuant hereto or thereto.

          Section 2. Grant of Security Interest.  As security for payment of all
Liabilities, the Executive hereby pledges, assigns and transfers to the Company,
and grants to the Company 

<PAGE>

a  continuing  security  interest  in and to,  the  Shares,  together  with  all
Dividends and Distributions, interest and other payments and rights with respect
thereto,  together with all proceeds thereof  (collectively,  the "Collateral").
The Executive further pledges,  assigns and transfers to the Company, and grants
to the  Company a  continuing  security  interest  in and to, and agrees to duly
endorse to the order of the Company,  any additional  Collateral,  together with
all proceeds thereof, delivered by the Executive to the Company for the purposes
of pledge under this Agreement. Any Collateral delivered by the Executive to the
Company may be endorsed  by the  Company,  in its own name or in the name of the
Executive, on behalf of the Executive to the order of the Company.

          Section 3. Stock Powers, Endorsements,  Etc. The Executive shall, from
time to time, upon request of the Company,  promptly  execute such  endorsements
and deliver to the Company such stock powers and similar documents, satisfactory
in form and  substance to the Company,  with  respect to the  Collateral  as the
Company may reasonably request and shall, from time to time, upon request of the
Company,  promptly transfer any securities which are part of the Collateral into
the  name  of  any  nominee  designated  by the  Company  on  the  books  of the
corporation or other entity issuing such securities; provided, however, that the
Company  shall not be entitled to effect or demand a transfer of the  Collateral
into the name of the Company or the Company's nominee without the consent of the
Executive unless and until a Default shall have occurred.

          Section  4.  Certain  Other  Agreements  Regarding   Collateral.   The
Executive shall deliver (properly endorsed where necessary) to the Company:

          (a) after a Default  shall have occurred and be  continuing,  promptly
upon receipt  thereof by the Executive  and without any request  therefor by the
Company, all Dividends and Distributions,  and other proceeds of the Collateral,
all of which shall be held by the Company as additional Collateral; and

          (b) at any time after a Default shall have occurred and be continuing,
promptly  upon  request of the  Company,  such  consents  or  proxies  and other
documents  as may be necessary to allow the Company to exercise any voting power
or other  right  with  respect to any  securities  included  in the  Collateral;
provided,  however, that unless a Default shall have occurred and be continuing,
the Executive shall be entitled:

               (i) to exercise,  as the Executive  shall deem  appropriate,  all
     voting  or other  powers  with  respect  to  securities  pledged  hereunder
     (including but not limited to the Shares); and

               (ii) to receive  and retain for the  Executive's  own account any
     and all Dividends paid in cash.

          Section  5.  Actions  Upon  Default.  Whenever  a Default  shall  have
occurred and be  continuing,  the Company may exercise from time to time any and
all rights and remedies  available to it under applicable law, including but not
limited  to all  rights of a secured  party 

<PAGE>

available to it under the Uniform  Commercial Code.  Without limiting the above,
the  Company  may  from  time  to  time,  whether  before  or  after  any of the
Liabilities  shall  become  due and  payable,  but only if a Default  shall have
occurred,  without  notice to the  Executive,  take any or all of the  following
actions:

          (a)  transfer all or any part of the  Collateral  into the name of the
Company or its nominee; and

          (b) execute (in the name, place and stead of the Executive) any or all
endorsements,  assignments,  stock powers and other instruments of conveyance or
transfer with respect to all or any of the Collateral.

          The Executive  understands that compliance with the Federal securities
laws,  applicable  blue sky or  other  state  securities  laws or  similar  laws
analogous in purpose or effect may  strictly  limit the course of conduct of the
Company  if the  Company  were to  attempt  to dispose of all or any part of the
Collateral  and may also  limit the  extent to which or the  manner in which any
subsequent  transferee of the Collateral  may dispose of the same.  Accordingly,
the  Executive  agrees that IF ANY  COLLATERAL  IS SOLD AT ANY PUBLIC OR PRIVATE
SALE,  THE  COMPANY  MAY ELECT TO SELL  ONLY TO A BUYER  WHO WILL  GIVE  FURTHER
ASSURANCES,  SATISFACTORY  IN FORM  AND  SUBSTANCE  TO THE  COMPANY,  RESPECTING
COMPLIANCE WITH THE REQUIREMENTS OF THE SECURITIES ACT OF 1933, AS AMENDED,  AND
ANY AND  ALL  APPLICABLE  STATE  SECURITIES  LAWS;  AND A SALE  SUBJECT  TO SUCH
CONDITION SHALL BE DEEMED  COMMERCIALLY  REASONABLE.  The Company shall have the
right to bid upon or purchase the Shares,  or any other part of the  Collateral,
or all of the foregoing, at any such sale, less any and all amounts owing to the
Company by the Executive under the Note,  this Agreement or otherwise,  and that
any such purchase is commercially reasonable.

          Section 6.  Application of Moneys.  Any moneys received by the Company
upon  payment to it of any  Collateral  held by it or as  proceeds of any of the
Collateral  may be applied by the Company  first to the payment of any  expenses
incurred by it in connection with the Collateral, including, without limitation,
reasonable attorneys' fees and legal expenses,  and all other amounts payable to
the Company by the Executive,  and any balance of such moneys so received by the
Company may be applied to all Liabilities of the Executive  (including,  without
limitation,  the principal  amount of the Note  outstanding  whether or not such
principal  amount is at that time due and payable) in such order of  application
as the Company in its sole discretion may determine. Any amounts remaining after
payment of the  Liabilities  may be applied by the Company to the payment of any
and all other  amounts  owing,  whether or not then due, to the Company from the
Executive and any remaining balance thereafter shall be paid to the Executive.

<PAGE>

          Section 7. Release of  Collateral.  Upon the  indefeasible  payment in
full of the Liabilities,  the Company shall,  upon the request of the Executive,
promptly  reassign and redeliver to the Executive the  Collateral  which has not
been sold,  disposed of,  retained or applied by the Company in accordance  with
the terms  hereof,  together  with such  endorsements,  stock powers and similar
documents  as the  Executive  may  reasonably  request.  Such  reassignment  and
redelivery shall be without warranty by or recourse to the Company, except as to
the  absence of any prior  assignments  by the  Company of its  interest  in the
Collateral.  In the event  that the  Executive  proposes  to sell,  transfer  or
otherwise  dispose of all or a portion of the  Shares,  upon the  request of the
Executive, the Company shall release from its security interest the Shares to be
sold by the Executive and, at the sole expense of the  Executive,  shall deliver
such  Shares  as  directed  by the  Executive,  free and  clear of any  security
interest  hereunder,  upon receipt from or on behalf of the Executive of the net
proceeds  of such sale,  transfer  or other  disposition  in cash in next day or
immediately available funds.

          Section 8.  Non-Recourse  Nature of  Liabilities.  The Company's  sole
recourse for the payment of the  Liabilities  shall be limited to the Collateral
securing  the  Note.  THE  COMPANY  SHALL  NOT HAVE THE  RIGHT  TO  ENFORCE  THE
LIABILITIES  AGAINST THE  EXECUTIVE  OR ANY OF THE  EXECUTIVE'S  OTHER ASSETS OR
PROPERTY.

          Section 9. Miscellaneous.

          (a) To the fullest extent  permitted by applicable law, this Agreement
shall continue to be effective or be  reinstated,  as the case may be, if at any
time any  amount  received  by the  Company in  respect  of the  Liabilities  is
rescinded  or must  otherwise  be restored  or returned by the Company  upon the
insolvency  or  bankruptcy  of the  Executive  or upon  the  appointment  of any
receiver, intervenor, conservator, trustee or similar official for the Executive
or any substantial part of his assets, or otherwise, all as though such payments
had not been made.

          (b) No remedy  herein  conferred  is intended to be  exclusive  of any
other remedy herein conferred or otherwise  available to the Company,  but every
such remedy shall be  cumulative  and in addition to every other  remedy  herein
conferred,  or conferred on the Company by any other  agreement or instrument or
now or hereafter existing at law, in equity or by statute.

          (c)  Any   provision  of  this   Agreement   which  is  prohibited  or
unenforceable  in  any  jurisdiction,   shall,  as  to  such  jurisdiction,   be
ineffective  to the  extent  of such  prohibition  or  unenforceability  without
invalidating  the  remaining  provisions  hereof,  and any such  prohibition  or
unenforceability   in  any   jurisdiction   shall  not   invalidate   or  render
unenforceable such provision in any other jurisdiction.

          (d)  Except  as  otherwise  expressly  provided  herein,  no  term  or
provision of this  Agreement  may be amended,  waived,  discharged or terminated
orally, but only by an instrument in writing signed by the parties.

          (e) THIS  AGREEMENT  AND ALL RIGHTS  HEREUNDER  SHALL BE  CONSTRUED IN
ACCORDANCE  WITH AND  GOVERNED  BY THE LAWS OF THE STATE OF NEW  JERSEY  WITHOUT
GIVING EFFECT TO THE CONFLICTS OF LAWS PROVISIONS THEREOF.  THE EXECUTIVE HEREBY
CONSENTS  AND  SUBMITS TO THE  EXCLUSIVE  JURISDICTION  OF THE FEDERAL AND STATE
COURTS LOCATED IN THE STATE OF NEW JERSEY HAVING SUBJECT MATTER  JURISDICTION IN
CONNECTION  WITH ANY AND ALL DISPUTES  ARISING OUT OF OR IN CONNECTION WITH THIS
Agreement, THE NOTE OR THE TRANSACTIONS CONTEMPLATED HEREBY OR THEREBY. FURTHER,
THE EXECUTIVE HEREBY CONSENTS AND AGREES THAT SERVICE OF PROCESS BY THE COMPANY,
OR ANY  PARTY  ACTING  ON BEHALF OF THE  COMPANY,  SHALL BE DEEMED  VALIDLY  AND
PROPERLY  EFFECTED  AGAINST  THE  EXECUTIVE  UPON THE  MAILING OF A COPY OF SUCH
PROCESS BY CERTIFIED MAIL, POSTAGE PREPAID,  TO THE EXECUTIVE AT ITS ADDRESS SET
FORTH ABOVE.

          (f) No course of dealing and no delay on the part of any party  hereto
in exercising any right,  power,  or remedy  conferred by this  Agreement  shall
operate as a waiver thereof or otherwise  prejudice such party's rights,  powers
and remedies hereunder or in connection herewith.  No single or partial exercise
of any power or remedy  conferred by this Agreement  shall preclude any other or
further exercise thereof or the exercise of any other right, power or remedy.

          (g) This  Agreement  shall inure to the benefit of and be binding upon
