Part. 5 – Calibration Guide BW GasAlertMicroClip XL Gas detector


Unlike other electrical or mechanical measuring equipment, gas detectors belong to consumable measuring equipment. Due to the reason that the sensor is electrolysed, each measurement, the amount of chemicals in the sensor will change, resulting in a response to a certain gas concentration also changes. That is why the manufacturer recommends calibration of your gas detector at least once every 6 months. And if the frequency of use is more, calibration of the machine more, like once a month.
