An NDIR sensor, Non-Dispersive Infrared Sensor, operates based on the infrared absorption of specific gases. Different gases absorb infrared radiation at characteristic wavelengths.
This physical principle is used to precisely determine the concentration of specific gases. The method is used, among other things, for measuring CO₂, carbon monoxide (CO), methane and other gaseous substances.
Reliably detects specific gases, even in complex gas mixtures.
Robust technology for stable measurement values over long periods of time.
Infrared absorption is a reliable and proven measurement method.
Available for numerous gases and concentration ranges.
The sensor typically consists of an infrared source, a measuring chamber, an optical filter and an infrared detector.
The infrared radiation is guided through the measuring chamber, which contains the gas to be analyzed. If the target gas is present in the chamber, it absorbs part of the radiation at its specific wavelength. The detector then measures the remaining intensity of the radiation. Based on this attenuation, the gas concentration can be determined.
Ideal for a wide range of applications in industry, environmental technology and research.
Monitoring and optimization of combustion and production processes.
Control of exhaust gases and emission values in industry and environmental technology.
Monitoring of biogas plants and energy production processes.
Analysis and investigation of gases in laboratories and research facilities.
Monitoring of CO₂ and VOCs for healthy indoor air.
Early detection of critical gases for increased occupational safety.
