Model: CO12
CO12 Standalone Carbon Monoxide Alarm
The CO12 standalone carbon monoxide alarm uses an electrochemical sensor to detect CO levels. Ambient air diffuses into the sensor through vents, generating a current proportional to concentration to trigger the alarm. It is certified by TUV as an ordinary carbon monoxide alarm and meets UL2075 and UL2034 standards.

The CO12 Standalone Carbon Monoxide Alarm monitors Carbon Monoxide by using an electrochemical sensor. Ambient air (containing carbon monoxide) slowly diffuses into the CO sensor through vents on the alarm casing. This generates an electric current: the reaction produces a tiny flow of electrons (current). The higher the concentration of carbon monoxide, the more molecules participate in the reaction, and the stronger the current produced. It is classified as an ordinary Alarm by TUV.
