The role of a pump-type gas detector

更新时间：2021-12-10 15:36:33 The role of a pump-type gas detector
If it is entering a confined space, such as a reaction tank, storage tank or container, sewer or other underground pipes, underground facilities, agricultural confined granaries, railway tank cars, shipping holds, tunnels and other working places, it must be tested before personnel enter, and it must be tested outside the confined space.
In this case, it is necessary to choose a pump-suction gas detector with a built-in sampling pump. This is because the gas distribution and gas types in different parts of the confined space (upper, middle, lower) are very different.
For example, the specific gravity of combustible gases in a general sense is light, and most of them are distributed in the upper part of the confined space; Carbon monoxide has the same specific gravity as air and is generally distributed in the middle of confined spaces. Heavier gases such as hydrogen sulfide are found in the lower part of confined spaces. At the same time, oxygen concentration is also one of the types that must be tested. 产品推荐：
