[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.
[Accurate measuring range]CO measuring range: 0 - 500 ppm; Humidity measuring range: 20% ~ 80% RH; Temperature measuring range: 14¢µ to 104 ¢µ(-10¡É to 40¡É). Large Color 2.2 inch 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]This 3 in 1 CO detector can Continue working 90 hours with full charge; Support working when charging to achieve long-time work. Include energy-save mode: Click inch B inch buttom to off the backlight.
[Color indicator light warning & Comfort emoji change & trill Alarm][CO ppm: 0-100, Green indicator light and smile emoji show]; [CO ppm: 100-200, Yellow indicator light and expressionless emoji show warning]; [CO ppm: 200-500, Red indicator light and sad emoji show with trill Alarm].
[Perfect design for outdoor and indoor]This 3 in 1 multi-functional carbon monoxide detector can be widely use like home, office, school, camping, picnic, outdoor adventure, in car etc.With portable design, we can put it on the desk, kitchen, near by fireplace, in bedroom, dining, field tent, even we can use it as hand-held air quality monitor.
