LFG202 Duct Carbon Dioxide Transmitter is based on different gases having 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 long life and good stability. The imported high-performance NDIR sensor is used for CO2 concentration measurement, with rapid response, stable performance and high accuracy; wide power supply range and high protection level of the shell, which can adapt to various harsh conditions on site. It can be widely used in the measurement of CO2 concentration in ducts, offices, factory workshops, laboratories and other environments.
Imported high-performance NDIR sensor.
The sensor is oxygen-free and has a service life of more than 5 years.
The internal waterproof and breathable membrane design effectively prevents water vapor from entering.
Good long-term stability and reliability, with ABC self-calibration.
