Atmospheric CO2 monitoring with NDIR-based analyzers

We anticipate that the benefits of the new laser-based instruments will often out-weigh their greater initial cost and will lead to their increasing use in atmospheric CO2 monitoring. However, it is important to describe and report the performance of current 5 NDIR systems because (1) data from these systems are supporting a wide range of

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 ...

Nondispersive infrared sensor - Wikipedia

A nondispersive infrared sensor (or NDIR sensor) is a simple spectroscopic sensor often used as a gas is non-dispersive in the fact that no dispersive element ( a prism or diffraction grating as is often present in other spectrometers) is used to separate out (like a monochromator) the broadband light into a narrow spectrum suitable for gas sensing.
