Gas Detectors require regular test and calibration to insure they accuracy detect gas(es), before they present a hazard. As gas sensors age, they lose their sensitivity. Exposure to gases and other environmental factors, can cause a gas sensor to loose sensitivity. Calibration compensates for this loss and adjusts the readings to the new sensitivity.
Safety Instruments uses gas mixtures that are NIST Weight Traceable. At your request, we will provide a calibration certificate for each gas detector we service. In addition to calibrating, we test each detector to insure they meet all manufacture performance specifications, as outlined in the manufacturers owner manual.
