An NDIR gas sensor (nondispersive infrared sensors) is a simple spectroscopic device often used as gas detector. It is called nondispersive because the wavelength which passes through the sampling chamber is not prefiltered. Instead a narrow bandpass (or NBP) filter is used before the detector. The NDIR sensor is a broadband IR detector using ...

Why NDIR? A nondispersive infrared (NDIR) sensor has a detector that measures how much infrared light of a specific wavelength is absorbed by the surrounding air. This measurement is then used to calculate the concentration of a specific gas. ›. Compared to electrochemical sensors, the lifespan of the NDIR sensor is lengthy.

Jan 22, 2021· NDIR Sensors Hydrocarbons. Despite the advantages they have over catalytic bead sensors, NDIR sensors are not without their limitations. Most notably, NDIR sensors cannot detect hydrogen because this gas does not absorb infrared light. Hydrogen is a potentially dangerous gas in many mining and petroleum extraction and processing environments.
