What checks should be done before using the gas detector
The detector should be calibrated and tested in time. No matter what the instrument is, it should be carefully checked and calibrated before use, especially for gas detectors. If timely calibration and testing are not carried out before use, the accuracy of the instrument itself may deviate. Therefore, it is very necessary to perform timely calibration and inspection before using the gas detector. So what kind of inspection should be done before the gas detector is used?
Before using the gas detector, the following checks should be done
1. Appearance power inspection: Before use, carefully check whether the appearance of the gas detector is intact or not. The detector should be turned on to see if it can self-check normally and then enter the detection interface, and observe whether the power of the detector can meet the work needs. If the power is insufficient, it should be charged immediately, and it is forbidden to bring it into the job site.
2. Use environment inspection: Before use, check the nameplate of the gas detector to clarify the type and range of the gas to be detected, the applicable temperature range, and 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 with more than 100% LEL, the sensor may be completely burned. For toxic gas detectors, working at a higher concentration for a long time will also cause damage to the sensor.
3. Alarm test: After the gas detector is turned on normally, use the corresponding gas cylinder to conduct a ventilation test to check whether the sensor response of the gas detector is sensitive and whether the alarm function is complete. If the detector does not respond after the air test, it should be repaired immediately.
