Carbon monoxide alarm is used to detect carbon monoxide gas (CO). It can not be used to detect alkanes such as methane (CH4). Gas alarms on the market are usually used to detect natural gas, liquefied petroleum gas or coal gas, etc., urban pipeline gas is usually one of these three gases. The main components of these gases are alkanes, such as methane (C4H4), whose main characteristic is a pungent odor.
When the concentration of these flammable gases in the air exceeds a certain standard, it can cause an explosion. The gas alarm detects this explosive alkane gas and can not be used to detect carbon monoxide gas. City pipeline coal gas is a rather special gas, which contains both the composition of CO, but also contains alkanes. If the use of coal stove heating, burning coal installation of gas alarm is no use, poisoning, gas alarm will not ring. This is quite dangerous. So if only to detect pipeline gas leaks, you can use carbon monoxide alarm detection can also be used gas alarm detection. However, if pipeline gas, liquefied petroleum gas or coal gas is to be tested for excess carbon monoxide gas during combustion, a carbon monoxide alarm is required.
In addition, coal-fired furnaces generate carbon monoxide gas (CO) instead of methane gases such as methane (CH4). So you should use a carbon monoxide alarm instead of a gas alarm. In short, if you are testing for toxic gases and are not concerned about poisoning, use a carbon monoxide alarm. If you want to detect the explosive gas, the concern is whether the pipeline leaks, the general use of gas alarm on it.
Therefore, when we choose the alarm must be sure to test the gas, Hua Fan Qin Lu main production: portable gas detector, pump gas detector, single-point wall-mounted gas detector, Transmitter / probe, bus gas transmitter / probe, gas control cabinet / host.
