How Do we Know Combustible Gas Detector Needs to Be Replaced?

The combustible gas detector with its high sensitivity and wide application scope can accurately detect some commonly-used combustible gases, such as CO and natural gases. How to tell the sensitivity of the combustible gas detector's sensor is impaired and when it should be exchanged might not be something easy.

The combustible gas detector follows the same gas detection principle adopted by other gas detectors. The combustible gas detector operates based on the gas sensor. After being used for a period of time, the combustible gas detector might encounter a series of problems. Particularly, when the detector is used for a long time, the sensitivity of the gas detector might drop. Therefore, it is necessary to change the sensor after being used for a period of time. Some users think that, each time the detector is used, the sensor should be changed. In fact, there is no need to change the sensor so frequently, and frequent change of the sensor might damage the original component settings, thus further damaging the sensitivity of the gas detector. After every detection, the sensor will display the reserved value. When the value display decreases, the sensor must be changed.
It is necessary to learn about the reserved value of the gas detector. The value marked on the equipment is the reserved value. If the reserved value displayed on the gas detector ranges from 50% to 70% of the gas concentration, then we should change the sensor of the gas detector. Therefore, it is tremendously important to change the gas detector's sensor immediately to avoid influencing our normal use of the gas detector.

Hence, the user should pay attention to the sensor's reserved value at any time. It is a very important judgment index. When the gas detector is used, it is impossible to ensure all functions are normal and to be correctly measured. In fact, to give full play to the role of different parts is the only way to ensure the gas detector's normal functioning. Among these parts, the sensor is a critical one, and we should immediately change it if it is damaged. If the sensor does not have adequate sensitivity to perceive the external changes, then it is necessary to replace the sensor to realize accurate measurement.
