Standards for the testing of gas detectors
Gas detectors can be used to detect gases produced in industrial applications, but their detection capabilities will be affected by usage time. In this case, the gas detector should be checked regularly. So what are the inspection standards for gas detectors?
Inspection standards for gas detectors:
1. Power-on inspection
The gas detector needs to be connected to the power supply during operation. Generally, the instrument is powered by a built-in battery. Before using the instrument, you can turn on the switch and check whether the power on state is normal. The gas detector can work by replacing the battery or equipped with a charger. Before using the gas detector of the charger, you need to test whether the charger can charge normally. When the instrument is powered on, you can check whether the display screen of the gas detector displays normally.
2. Check appearance and other items
We can check the appearance of the gas detector to see if there are any problems with the gas detector during transportation or assembly. We can check whether there are flaws, cracks or damage in the appearance of the gas detector, and check whether the overall structure of the instrument is complete. And you should check the gas detector's machine model, label, manufacturer's name, factory date and instructions, etc., and make sure it is consistent with the manufacturer's information. In addition, you also need to check the explosion-proof mark, measurement license mark and instrument of the gas detector. Information such as serial number can generally be requested from the manufacturer before purchasing the instrument.
3. Check whether the sound and light alarm function of the instrument is normal.
Some gas detectors have audible and visual alarm functions. Since they are powered by batteries, when the battery is in an under-voltage display state, the alarm signal sent by the instrument should be significantly different from that of the instrument under normal power supply.
The above inspection standards for gas detectors are shared here. Gas detectors can be widely used in petroleum, chemical industry, coal, etc. During production, processing and transportation, various flammable and explosive gases or liquids may appear. Leaky industry.
