All our instruments are regularly (every 6 months or less) calibrated by E & E Process Instrumentation, 400 North Rivermede Rd., Concord, Ont.

Each DEI field technician caries a binder with the copy of updated Calibration Certificates for all instruments in his possession-the originals are kept on file in our main office. Each technician has a complete set of basic instruments; only specialty instruments are shared.
