CO2 Sensor CM1109

CO2 Sensor CM1109


NPI-New Product Information

Cubic patented two-engine dual beam NDIR CO2 sensor CM1109 is used to detect CO2 concentration of indoor air by adopting infrared (NDIR) technology. With higher accuracy and better stability, it is widely used for ventilation system, air purifier, air conditioner, intelligent agriculture, storage and cold-chain, etc.

This product also has excellent dual-channel performance, but it is better cost effective than dual channel.
