Can toxic gas and combustible gas be detected at the same time?


We need to know what is the difference between these two gases. Combustible gas means that it can be uniformly mixed with air or oxygen within a certain concentration range to form a premixed gas. It will explode when encountering a fire source, and a large amount of energy will be released during the combustion process gas.
Toxic gas, as the name implies, is a gas that is harmful to the human body and can cause poisoning. Can toxic gas and combustible gas be tested at the same time? When these two gases are combined, they are dual gas, which is both flammable and toxic. In this case, the difference is that the catalytic combustion detection principle is used to measure the combustible gas, and the lower limit of explosion is measured. Toxic uses electrochemical principles, which measure the concentration-to-volume ratio. The reaction is fast and the detection is more accurate. Of course, the price is higher.

Of course it is possible. The state stipulates that dual gases need to be detected to be toxic, so when detecting these two gases at the same time, it is enough to determine the main detection principle of the gas detector.
