Gas detectors need to do before use what checks
Detectors should be calibrated and tested in a timely manner. No matter what the instrument, should be done before the use of careful checking and calibration, gas detector is especially so, in the use of the instrument itself may be deviated from the accuracy of the instrument if it is not calibrated and tested in a timely manner before use, therefore, in the use of gas detector before the use of timely calibration and inspection is very necessary. So what kind of check is specifically needed before using the gas detector? Here to share the following points.
Gas detectors need to do the following checks before use
1, the appearance of the power check: before use, should carefully check whether the appearance of the gas detector is intact, the detector should be switched on to see whether it is able to normal self-test into the detection interface, to observe whether the detector power to meet the needs of the work. If the power is insufficient, it should be charged immediately and prohibited to bring into the work site.
2, the use of environmental checks: before use should check the nameplate of the gas detector, clear detection of the type of gas and range, temperature range, explosion-proof applicable areas, etc., different gas detectors have a specific use of the range, in excess of the use of the range of environments, will be working in the gas detector will cause damage to the detection of the function may be seriously lost. For example, gas LEL detector, if accidentally used in more than 100% LEL environment, it is possible to completely burn the sensor. And toxic gas detector, working for a long time in higher concentrations will also cause sensor damage
3, alarm test: to be a gas detector normal power on, the corresponding gas cylinder should be used to gas test, check the gas detector sensor response is sensitive, the alarm function is complete. If the detector does not respond after the gas test, it should be returned for repair immediately.
