Ways to determine if a gas detector is malfunctioning
Gas detectors are used to detect the concentration value of gases, and the reason why it is necessary to detect the concentration value of gases is to prevent excessive toxic and harmful gases or flammable and explosive gases from accumulating in the air of the local area, which may cause dangerous accidents. In addition, it can also be used to detect the presence of gas leakage conditions in equipment, pipelines and other carriers that produce storage and transport gases. How to judge whether the gas detector failure? What are the methods? In response to this question
1. Display error codes
Check whether the instrument displays an error code or fault indication, directly reflecting the fault.
2. Inaccurate test
Use the standard test gas for testing, the result is too large deviation from the standard value may be damaged.
3. Can not start normally
The detector can not start normally, the display does not light up, etc., may be a circuit failure.
4. Calibration failure
If the calibration of the gas detector cannot be completed according to the standard procedure, it is likely to be a malfunction.
5. No response
The detector is not responsive to different concentrations of gases, and the response reading is abnormal.
6. Unstable results
The results fluctuate greatly, the same sample is measured continuously but the readings are too different.
7. Damaged appearance
Check whether there is mechanical damage to the instrument shell, probe, display.
8. Probe connection failure
Determine whether the probe is connected abnormally, resulting in signal interruption.
