II. Working Principle
NDIR Infrared Absorption: CO2 has strong absorption at specific
wavelengths of infrared light, and the higher the concentration,
the stronger the absorption. The attenuation of light intensity is
proportional to the concentration.
Dual Beam / Dual Wavelength: The reference channel compensates for
light source drift, dust, temperature and humidity interference,
ensuring long-term stability and maintenance-free operation.
No Consumption, No Poisoning: It does not react with gases and is
not affected by H2S, VOC, etc., suitable for complex industrial
environments.
