The Mercury COD-218A offers timely warning in case of the presence of the dangerous carbon monoxide (CO), protecting against an invisible yet deadly hazard. It is equipped with a high-precision electromechanical sensor that continuously monitors the atmosphere, while the built-in LCD screen displays the CO levels in the air in real time. When it detects dangerous levels, it activates an 85dB audible alarm and a red indicator light.

The unit is standalone and battery-operated, so it remains active even during a power outage, and features a secure mounting system that prevents installation without batteries. It has been tested and certified in the United Kingdom, ensuring reliability and compliance with the strictest safety standards (EN50291-1:2018).
