Not sure how to choose a gas detector?

Carbon monoxide alarms and gas alarms are very different, and many people often confuse the two. In fact, the difference between the two is very big. If you are not careful, you will install a gas alarm by mistake in the occasion where you need to use a carbon monoxide alarm, and install a carbon monoxide alarm in the place where the gas alarm should be installed, which will bring harm to people’s lives and property. great loss.

Carbon monoxide alarms are used to detect carbon monoxide gas (CO). It cannot be used to detect alkane gases such as methane (CH4). The gas alarm is to detect natural gas, that is, the main component of methane gas. It is used for explosion detection, and carbon monoxide is used for poison detection. The sensor types are different. Gas uses catalytic combustion sensors, and carbon monoxide uses electrochemical sensors.

Gas alarms on the market can usually be used to detect natural gas, liquefied petroleum gas or coal-based gas, etc. The city pipeline gas is usually one of these three gases. The main components of these gases are alkane gases such as methane (C4H4), which are mainly characterized by a pungent odor. When the concentration of these combustible gases in the air exceeds a certain standard, it will cause an explosion. It is this explosive alkane gas that the gas alarm detects and cannot be used to detect carbon monoxide gas.

Coal-to-gas in urban pipelines is a special kind of gas, which contains both CO and alkane gases. Therefore, if it is only to detect whether there is leakage of pipeline gas, it can be detected with a carbon monoxide alarm or a gas alarm. However, if you want to detect whether the pipeline natural gas, liquefied petroleum gas or coal-based gas produces excessive carbon monoxide gas during combustion, you need to use a carbon monoxide alarm to detect. In addition, heating with a coal stove, burning coal, etc. produces carbon monoxide gas (CO), not alkane gas such as methane (CH4). So carbon monoxide alarms should be used instead of gas alarms. If you use a coal stove for heating and burning coal, it is useless to install a gas alarm. If someone is poisoned, the gas alarm will not sound. This is quite dangerous.

Under normal circumstances, if you want to detect a toxic gas, and you are concerned about whether it will be poisoned, then you should choose a carbon monoxide alarm. If you want to detect an explosive gas, the concern is whether it will explode. Then choose a gas alarm. Whether the pipeline is leaking, generally use a gas alarm.
