The ANW201G wall mounted carbon dioxide transmitter is based on the different absorption capabilities of different gases for specific infrared light bands. By measuring the degree of infrared light absorption, the concentration of the measured gas is measured. Compared with electrochemical sensors, it has the characteristics of long lifespan, good stability, wide power supply range, and anti reverse connection protection. Suitable for indoor air quality testing, air conditioning, air purifiers, vegetable greenhouses, and other occasions for measuring carbon dioxide gas.

Features & Benefits:

●   High linearity and stability

●   Good repeatability and long service life

●   High-precision electrochemical sensor, no need for on-site calibration and       replacement

●   Double-layer waterproof membrane design effectively prevents water                vapor from entering, and the sensing element is non-toxic
