Independent Carbon Monoxide Sensor Detector Alarm

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)
