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.
III. Main Applications (Industrial Safety Specialized)
Confined Space Monitoring: Sewers, tanks, ship holds, underground CO2 safety detection
Industrial Safety Alarm: Food fermentation, beer, carbonated beverages, cold storage CO2 leakage
Greenhouse / Agriculture: Greenhouse CO2 concentration control (compatible with industrial range)
Environmental Emission: Boiler, kiln, exhaust gas CO2 online monitoring
Fire / Rescue: CO2 concentration assessment after fire, personnel safety protection
Petrochemical: Process monitoring, inert gas protection CO2 monitoring
