The sensors in various gas detectors have a certain service life. Among gas detectors, LEL (flammable gas) sensors have a long lifespan, generally about three years of service; The lifespan of electrochemical gas sensors is relatively short, usually one to two years.
The lifetime of an electrochemical sensor depends on the drying of the electrolyte in it. Therefore, if it is not used for a long time, it can be sealed in a lower temperature environment to extend its service life. Due to the relatively large size of the fixed instrument, the sensor life is also longer. Therefore, the sensor should be detected at all times and pay special attention to the service life.
