Why NDIR? | Senseair

+

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.
