• Using advanced semiconductor sensors and electrochemical sensors, it can detect and monitor carbon monoxide gas and smoke sensitively
• Keep your family safe with this carbon monoxide alarm
• When the carbon monoxide detector detects that the concentration of carbon monoxide reaches a dangerous level, the green light will flash and the alarm will sound at loudly sound volume(≥75dB)
• Equipped with an HD digital display screen, allowing you to easily read the carbon monoxide concentration
• Requires no wiring so you can easily install it in minutes without electricians on the wall or anywhere at home
