Carbon Monoxide Detectors Portable Temperature Detector Humidity Sensor Air Meter Smoke CO Gas Monitor Alarm

NDIR working method & 3 in 1 function: Our carbon monoxide detector is based on the principle of non dispersive infrared absorption 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.

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.

High performance CO detector: Dimensions: 8.3.*3.2*8.3 cm. This CO detector is a high quality air quality detector, it features high accuracy, stable performance, jamming prevention, and low consumption. Don't hesitate to choose this beautiful shape carbon monoxide detector, and discard those traditional products without aesthetic feeling!
