The purpose of gas detection is mainly 2 types: one is explosion-proof, to prevent the gas from leaking out and mixing with air to form an explosive environment, and the other is to prevent the gas from leaking out and causing human inhalation to affect health and even life. There are also some gases that serve both purposes, such as ammonia. The explosion-proof gas detection range is 0-100% LEL, and the anti-virus gas detection range is 0-tens (or hundreds) ppm, which is quite different.
There are three types of hazardous gases: 1. non-toxic (or low-toxic) and combustible; 2. non-combustible and toxic; 3. combustible and toxic. The first and second situations are easy to determine, the first is measure the explosion, the second is measure the poison, third, if there are people exposed, the explosion can be measured if no people are exposed. Select combustible gas alarm controller for explosion test, and toxic gas alarm controller for poison test.
