LEFOO LFG201 wall-mounted carbon dioxide transmitter is based on the fact that different gases have different absorption capabilities for infrared light in a specific band. It measures the concentration of the measured gas by measuring the degree of infrared light absorption. Compared with electrochemical sensors, it has the characteristics of long life, good stability, wide power supply range and power supply anti-reverse connection protection. It is suitable for carbon dioxide gas measurement in indoor air quality detection, air conditioners, air purifiers, vegetable greenhouses and other occasions.
Features
* Imported infrared light source and dual-channel thermopile detector
* The sensor is oxygen-free and has a service life of more than 5 years
* Long-term stability and reliability
* Double-layer waterproof membrane design effectively prevents water vapor from entering
