The correct way to use a combustible gas detector is as follows
According to national requirements, gas detectors that are essential for safety production are important alarm devices that can effectively prevent explosion and poisoning accidents caused by gas leaks. Since it's so important, how can we make a purchase? Below is a brief analysis of the judgment methods for purchasing similar equipment!
Everyone should have a question, how can I determine if a combustible gas detector works well after buying it? In fact, this method is very simple. Generally, workshops store experimental gas. We only need to put some gas or liquid into mineral water bottles, screw on the lid, and insert a small hole with a pointed object on the lid. Align this small hole with the probe of the combustible gas detector, and you can see whether the reading on the gas detector panel has changed.
Special attention should be paid to the fact that some combustible gases are in a liquid state and volatilize slowly. Therefore, in the experiment, it is necessary to shake the mineral water bottle to accelerate its volatilization. Another point: Fixed gas detectors generally have natural diffusion, and the equipment will only react when the leaked gas diffuses to the alarm device.
If you feel that this method is inconvenient, you can use a lighter to test whether the gas detector can read. Method: Turn on the lighter and blow out the fire, but do not let go of your hand so that the lighter is still in a deflated state. Align the lighter with the gas detector probe, but do not wait too long because the combustible gas concentration of the lighter is very high, and if the time is too long, it can easily cause the gas concentration to exceed the range of the gas detector. If this is done for a long time, it can easily shorten the service life of the gas detector.
If you want to know if the gas detector is reading accurately, it can be a bit difficult. At this point, we must know the concentration of the gas we are using and check if the reading of the gas detector matches the concentration value we know (national standards allow for partial errors). If it is consistent or the difference is very small, it indicates that the gas detector can read correctly.
