What inspections do you need to do before using a gas detector?

Gas detectors can meet the detection needs of various environmental leaks. When the gas concentration value exceeds the standard, the instrument will automatically sound an alarm to remind personnel to protect themselves. So what inspections do you need to do before using a gas detector?

1. Use environment inspection: Before use, check the nameplate of the gas detector to clarify the type and range of the detected gas, the temperature range, the explosion-proof applicable area, etc. Different gas detectors have specific use ranges. Working in an environment beyond the use range will cause damage to the gas detector, and may seriously lose the detection function. For example, if a combustible gas LEL detector is accidentally used in an environment exceeding 100% LEL, it may completely burn the sensor. For toxic gas detectors, long-term use at higher concentrations will also cause damage to the sensor.

2. Appearance power inspection: Before use, carefully check whether the appearance of the gas detector is intact and undamaged. The detector should be turned on to see if it can enter the detection interface after normal self-test, and observe whether the detector power can meet the work needs. If the power is insufficient, it should be charged immediately and it is forbidden to bring it into the work site.

3. Alarm test: After the gas detector is turned on normally, the corresponding gas cylinder should be used for ventilation test to check whether the gas detector sensor responds sensitively and whether the alarm function is complete. If the detector does not respond after the ventilation test, it should be returned for repair immediately.

To sum up, these are the checks that the gas detector needs to undergo before use. The gas detector can quickly and accurately detect a variety of different gases and display the gas content and concentration. If toxic gases are detected, it will promptly remind the staff to ensure people's safety.
