ELECTRIC & GAS TECHNOLOGY, INC. AND SUBSIDIARIES

Exhibit 31.2

I, George M. Johnston, certify that:

     1.   I have reviewed this  quarterly  report on Form 10-Q of Electric & Gas
          Technology, Inc.;

     2.   Based on my  knowledge,  this  quarterly  report  does not contain any
          untrue  statement of a material  fact or omit to state a material fact
          necessary to make the statements  made, in light of the  circumstances
          under which such  statements were made, not misleading with respect to
          the period covered by this quarterly report;

     3.   Based on my knowledge,  the  consolidated  financial  statements,  and
          other financial  information included in this quarterly report, fairly
          present in all material respects the consolidated financial condition,
          results of operations and cash flows of the registrant as of, and for,
          the periods presented in this quarterly report;

     4.   The registrant's  other  certifying  officer and I are responsible for
          establishing  and maintaining  disclosure  controls and procedures (as
          defined  in the  Exchange  Act  Rules  13a-  14 and  15d-  14) for the
          registrant and have:

          a)   designed such  disclosure  controls and procedures to ensure that
               material  information  relating to the registrant,  including its
               consolidated  subsidiaries,  is made known to us by others within
               those  entities,  particularly  during  the  period in which this
               quarterly report is being prepared;

          b)   evaluated  the  effectiveness  of  the  registrant's   disclosure
               controls and  procedures as of a date within 90 days prior to the
               filing date of this quarterly report (the "Evaluation Date");

          c)   presented  in this  quarterly  report our  conclusions  about the
               effectiveness of the disclosure  controls and procedures based on
               our evaluation as of the Evaluation Date; and

          d)   disclosed in this report any change in the registrant's  internal
               control  over  financial   reporting  that  occurred  during  the
               registrant's  most  recent  fiscal  quarter  that has  materially
               affected,  or is  reasonably  likely to  materially  affect,  the
               registrant's internal control over financial reporting;

     5.   The registrant's other certifying officer and I have disclosed,  based
          on our most recent  evaluation,  to the registrant's  auditors and the
          audit  committee  of  registrant's  board  of  directors  (or  persons
          performing the equivalent functions):

          a)   all  significant  deficiencies  in the  design  or  operation  of
               internal  controls which could adversely  affect the registrant's
               ability to record,  process,  summarize and report financial data
               and have  identified for the  registrant's  auditors any material
               weaknesses in internal controls; and

          b)   any fraud,  whether or not material,  that involves management or
               other employees who have a significant  role in the  registrant's
               internal controls.
