Carbon monoxide alarms can be divided into industrial and household carbon monoxide alarms. Industrial carbon monoxide alarms are expensive, require very high precision, and have small temperature and zero-point drift. In some special occasions, explosion-proof enclosures are often required. Industrial carbon monoxide alarms must use electrochemical sensors.

Home carbon monoxide alarms are mainly used in ordinary homes, small entertainment places, small factories and small chemical laboratories, etc., with relatively small appearance and relatively low price. In the past few years, both industrial and household carbon monoxide alarms mainly relied on imports. Since 2007, my country's self-produced and self-sold carbon monoxide alarms have only begun to increase. my country has been engaged in the research and design of electrochemical carbon monoxide sensors and alarms earlier.
