How to use the combustible gas detector correctly
According to national requirements, the gas detector, which is necessary for safe production, is an important alarm device, which can effectively avoid explosion poisoning accidents caused by gas leakage. Since it is so important, how do we buy it? The following is a brief analysis for everyone, the judgment method for purchasing similar equipment!
Everyone should have a question, after buying a combustible gas detector, how can I judge whether it is easy to use? In fact, this method is very simple. The general workshop will save the experimental gas. We only need to put part of the gas or liquid in the mineral water bottle, screw on the cover, insert a small opening on the cover with a pointed object, and align the small opening with the combustible gas. You can see whether the reading on the panel of the gas detector changes by checking the probe part of the gas detector.
Pay special attention to the fact that some combustible gases are in a liquid state and volatilize slowly, so in the test, it is necessary to shake the mineral water bottle to accelerate volatilization. Another point: fixed gas detectors generally diffuse naturally, and the equipment will respond only when the leaked gas diffuses to the alarm equipment.
If you feel that this method is troublesome, you can use a lighter to test whether the gas detector can read. Method: Light the lighter and blow out the fire, but do not let go of your hand, so that the lighter is still in the state of deflation, and aim at the probe of the gas detector, but do not take too long, because the concentration of flammable gas in the lighter is too high, and the time is too long , It is easy to cause the gas concentration to be too high, exceeding the range of the gas detector. If this is the case for a long time, it is easy to cause the life of the gas detector to be shortened.
It's a little more difficult to know if your gas detector is reading correctly. At this time, we must know the concentration of the gas we are using, and see if the reading of the detector is consistent with the concentration value we know (national standard, allowing some errors). If it is consistent or the difference is small, it means that the gas detector can read correctly.
