Application

Tips: Why do gas detectors need to be calibrated?

The accuracy of the combustible gas detector is an important prerequisite for detecting and issuing an alarm, and its accuracy depends on the built-in combustible gas sensor, whether it is an electrochemical sensor or a catalytic combustion sensor, it will be affected by certain environmental conditions during use. The influence of substances, and gradually changes or even poisoning failure, only through timely maintenance and calibration, the accuracy of the results detected by the instrument can be guaranteed. In actual use, many factors will affect the accurate value of the alarm. Regular calibration is to minimize the error of the detection result and achieve the highest accuracy.
