Keeping your gas monitors calibrated is crucial to worksite safety. All sensors gradually degrade over time; diminishing a sensor's ability to measure gas concentrations accurately. Performing regular calibrations adjust the instrument to compensate for this decline in sensitivity. During calibration, the installed sensors are exposed to expected concentrations of calibration gases and, when needed, the instrument will self-adjust to ensure the accurate measurement and display of gas concentration values. When a sensor has degraded beyond an acceptable level, no further adjustment is possible, and the sensor will no longer pass calibration. At this point the sensor will need to be replaced.
