Calibration Gas is a certified gas mixture, also referred to as span gas.
The gas (known concentration) is used to ensure gas detectors or meters are working properly.
Gas detectors or meters are used to check gas levels in areas that are considered hazardous. The detectors or meters require calibration on a routine basis. By introducing a known concentration of gas to the detector or meter's sensor, the unit is then verified to be functioning properly.
