The difference between a carbon monoxide gas detector and a flammable gas detector
Carbon monoxide detectors are very different from combustible gas detectors, and many dealers and users often confuse the two. In fact, there is a big difference between the two. If you are not careful, you will mistakenly install a combustible gas detector where a carbon monoxide detector is needed, and install a carbon monoxide detector where a combustible gas detector should be installed, which will save people's lives. Great loss to property.
The carbon monoxide detector is used to detect carbon monoxide gas (CO). It cannot be used to detect alkanes such as methane (CH4).
Combustible gas detectors on the market can usually be used to detect natural gas, liquefied petroleum gas or coal-based gas, etc. Urban pipeline gas is usually one of these three gases. The main components of these gases are alkanes such as methane (C4H4), and their main feature is a pungent smell. When the concentration of these flammable gases in the air exceeds a certain standard, it will cause an explosion. The combustible gas detector is this kind of explosive alkane gas, which cannot be used to detect carbon monoxide gas.
Urban pipeline coal gas is a special kind of gas, which contains both CO and alkanes. Therefore, if it is only to detect whether there is leakage of pipeline gas, either a carbon monoxide detector or a combustible gas detector can be used. However, if you want to detect whether excessive carbon monoxide gas is produced during the combustion of pipeline natural gas, liquefied petroleum gas or coal gas, you need to use a carbon monoxide detector. In addition, heating with coal stoves, burning coal, etc. produce carbon monoxide gas (CO), not methane (CH4) and other alkanes. Therefore, a carbon monoxide detector should be used instead of a combustible gas detector. It is useless to install a combustible gas detector in a place where a coal stove is used for heating or burning coal. If a person is poisoned, the combustible gas detector will not sound. This is quite dangerous.
