- - 【Electrochemistry working method & 3 in 1 function】Our carbon monoxide detector is based on the principle ofElectrochemistry, 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,we can see the gas ambient level is good or not actual time.
- - 【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.
