CDT71 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 I ight absorption.
Compared with electrochemical sensors, it has the characteristics of long life and good stability,
wide power supply range and power supply antireverse connection protection. It is suitable for
indoor air quality detection, air conditioners, air purifiers, vegetable green houses and other
occasions to measure carbon dioxide gas.
