Our Services

Gas Detectors require regular calibration. These meters have sensors that are similar to a battery in design.  Sensors have a typical shelf and working life of 2-3 years. We use NIST Weight Traceable gas standards, as specified by the manufacturer, to calibrate each gas detector we service. OSHA outlines the verification and calibration of direct reading portable gas monitors, at the following link Calibrating and testing of Direct-Reading Gas Monitors

We provide free technical phone support to all our customers. Our factory trained service technicians can answer your questions and provide you with the information and equipment you need for your application.
