CO2 monitor LFG201

CO2 monitor, or co2 sensors,  carbon dioxide monitor, carbon dioxide detector, is a digital carbon dioxide concentration monitoring device. The LFG series CO2 monitor is based on the different absorption capabilities of different gases for specific wavelengths of infrared light. 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 and good stability. Suitable for indoor air quality testing, air conditioners, air purifiers, vegetable greenhouses, and other occasions precision gas measurement and control. 



Features


* The sensor is oxygen-free and has a long service life

* Adopt imported infrared light source and dual-channel thermopile detector

Description of Co2 Transmitter LFG201

  • High linearity with temperature compensation

  • The sensor has no oxygen dependence and has a long service life

  • Adopt imported infrared light source and dual-channel thermopile detector

  • The double-layer waterproof membrane design effectively prevents water vapor from entering, and the sensing element is not poisonous

Application of Carbon Dioxide Transmitter

The CO2 Transmitter Shows the carbon dioxide (CO2) concentration in the ambient air as a measure for indoor air quality. A common application is for the HVAC system and construction industries. Rail transit project
