Carbon monoxide announciator, electrochemical sensors, combined with the living environment of people, through scientific design, the detection signal is very sensitive and accurate.

Features:

• A carbon monoxide detector using high-performance microcontroller can detect low to several PPM concentrations of carbon monoxide.
• Resetting two key tests is simple and convenient, and you can restart or to test environment of carbon monoxide concentration at any time.
• Just as the size of a hand is very convenient to test at different places.
• Adopt ultra-low power consumption, use 3 pieces of AA batteries, and the battery can be used for more than 2 years in a normal working environment.
• Powered by= 3 x AA Batteries (Not included)
