CO2 measurement with NDIR co2 sensors

Measuring method. The E+E CO2 sensors feature the dual wavelength/dual detector NDIR principle. One detector is tuned to µm wavelengths, which is absorbed by CO2, the second detector on µm, which is not affected by any gas. For every single measurement the CO2 concentration is calculated from the outputs of the two detectors.

CO2 Sensor Calibration: What You Need to Know |

Most of our CO2 products use non-dispersive infrared (NDIR) carbon dioxide sensors. These rely on an infrared light source and detector to measure the number of CO2 molecules in the sample gas between them. Over many years, both the light source and the detector deteriorate, resulting in slightly lower CO2 molecule counts. The industry calls this "drift". To combat sensor drift, during ...
