The main component of the carbon monoxide detector is the gas sensor, which can be mainly divided into four types of carbon monoxide detection sensors: electrochemical sensors, catalytic combustible gas sensors, solid-state sensors and infrared sensors.

The carbon monoxide detector mainly used in the market is an electrochemical gas detector. This carbon monoxide detector is controlled by a powerful microprocessor. It is converted into an electrical signal and displayed intuitively on the LCD screen. When the concentration of the measured gas in the environment reaches or exceeds the preset alarm value, the alarm immediately sends out an audible and visual alarm, and the LCD screen displays the current concentration value.

Carbon monoxide detector adopts solid engineering plastic shell and good protection design. The instrument is small and light and can be easily clipped on the belt, shirt pocket or helmet. The super large LCD liquid crystal display can clearly read the gas concentration, type, peak value and high and low concentration alarm levels. If the current high and low gas concentration values exceed the preset limit value, the instrument will remind the user with sound, light and vibration alarm.
