Common fault causes of gas detectors
1. If the sensor in the gas detector is damaged, no matter what changes in the gas concentration in the air, the displayed data will not change any more. In order to ensure the normal operation of the gas detector, it is necessary to perform regular and rapid detection. Failure to do so may result in biased measurement results.
2. Harsh environment and severe vibration will cause damage to the instrument. If the gas concentration in the currently applied environment exceeds the detectable range of the instrument, the sensor will also be damaged. And the filter membrane and the sensor port will also be polluted by liquid, impurities or dust, which will seriously affect the measurement degree. At this time, the calibration may become invalid.
3. The detection environment is harsh, the ambient temperature changes greatly, or it needs to be exposed to seawater or humid heat for a long time. These environments have high requirements on the stability of the gas detector. Long-term use in these environments may cause the gas detector to fail, and general instruments cannot be used in such extreme environments for a long time.
