DESCRIPTION

The LFG202 Duct Carbon Dioxide Transmitter, utilizing the principle that different gases exhibit distinct absorption capabilities for infrared light within a specified wavelength range, accurately measures the concentration of the target gas by assessing the degree of infrared light absorption. This LEFOO duct mounted CO2 sensor, renowned for its long lifespan and excellent stability compared to electrochemical sensors, employs an imported high-performance NDIR sensor for swift, stable, and precise CO2 concentration measurement.

With its wide power supply range and high-level shell protection, the LFG202 is designed to adapt to various harsh conditions, making it a suitable choice for industrial environmental monitoring. Whether it's ducts, offices, factory workshops, laboratories, or other environments, this digital CO2 monitor ensures reliable and accurate CO2 level detection, playing a crucial role in HVAC systems as a carbon dioxide sensor.
