A251 Wall-mounted CO2 Transmitter
This product is suitable for indoor air quality testing, air conditioning, air purifiers, vegetable greenhouses, and other occasions for measuring carbon dioxide gas.
The A251 Wall mounted CO2 transmitter is based on the fact that different gases have different absorption abilities for specific bands of infrared light. By measuring the degree of absorption of infrared light, the concentration of the measured gas can be measured. Compared with electrochemical sensors, it has the characteristics of long lifespan, good stability, wide power supply range, and anti reverse power protection.
