【NDIR working method & 3 in 1 function】Our carbon monoxide detector is based on the principle of non dispersive infrared absorption (NDIR), to detect carbon monoxide in the air, capture the weak current generated by electrochemical reaction, detect the concentration of carbon monoxide accurately and quickly by every 2 seconds actual time. This multi-functional CO detector integrated CO / Temperature / Humidity detection functions, so that we can see the gas ambient level is good or not.
【Accurate measuring range】CO measuring range: 0 – 500 ppm; Humidity measuring range: 20% ~ 80% RH; Temperature measuring range: 14℉ to 104 ℉(-10℃ to 40℃). Large Color 2.2” circular HD display with value of carbon monoxide / humidity / temperature / and a cartoon face. Super large CO value typeface, You can confirm the carbon CO concentration at a glance.
【Built-in high capacity 2400mAh battery】 With 2400mAh battery, this 3 in 1 CO detector can Continue working 90 hours with full charge; still support working when charging, which make this CO detector available working in varies occasions to prevent carbon monoxide-poiso`ning.
