Gas Detector Usage Notice

First, pay attention to the regular calibration and detection: toxic and harmful gas detectors are the same as other analysis and detection instruments, and they are measured by a comparative method. Therefore, zero calibration of the instrument at any time, and regular calibration of the instrument is an indispensable task to ensure accurate measurement of the instrument.

Second, pay attention to the detection of interference between various sensors: In general, each sensor corresponds to a specific detection gas, therefore, when selecting a gas sensor, it should be as far as possible to understand the interference of other gases on the detection of the sensor .

Third, pay attention to the life of various types of sensors: In general, in the portable instrument, the life of the LEL sensor can generally be used for about three years; the life of the photoionization detector is four years or more; the specific gas sensor of the electrochemical The service life is generally one to two years; the life of the oxygen sensor is about one year. The life of the electrochemical sensor depends on the dryness of the electrolyte, so if it is not used for a long time, sealing it in a lower temperature environment can prolong the service life. Because of the relatively large size of the stationary instrument, the life of the sensor is longer.

Fourth, pay attention to the measuring instrument concentration measurement range: all types of toxic and harmful gas detector has its fixed detection range. Only when the measurement is completed within its measurement range can the instrument be accurately measured.
