How to determine whether gas detector equipment is easy to use
Combustible gas detector is an important alarm device that can effectively prevent explosion and poisoning accidents caused by gas leakage. Since it's so important, how can we make a purchase? Below, the gas detector editor will briefly analyze how to determine whether the gas detector equipment is working properly.
Everyone should have a question, how can I determine if a combustible detector is effective after purchasing it? In fact, this method is very simple. Most workshops will store experimental gases. We just need to put some gas or liquid into a mineral water bottle, screw on the lid, insert a small hole with a pointed object on the lid, and align this small hole with the probe of the combustible gas detector to see if the reading on the gas detector panel has changed.
Special attention should be paid to the fact that some combustible gases are in liquid form and evaporate slowly. Therefore, in the experiment, it is necessary to shake the mineral water bottle to accelerate their evaporation. Another point: Fixed gas detectors are generally naturally diffusing, and the equipment will only react when the leaked gas spreads to the alarm device.
If you find this method troublesome, you can use a lighter to test whether the gas detector can read. Method: Use a lighter to extinguish the fire, but do not release your hand to keep the lighter in a deflated state. Aim the lighter at the gas detector probe, but do not hold it for too long, as the combustible gas concentration in the lighter is very high. Prolonged use can easily cause the gas concentration to exceed the range of the gas detector, which can shorten the lifespan of the gas detector.
It's a bit difficult to know if the gas detector is reading accurately. At this point, we must know the concentration of the gas we are using and check if the readings from the gas detector are consistent with the concentration values we know (according to national standards, some errors are allowed). If they are consistent or have a small difference, it indicates that the gas detector can read correctly.
