Why NDIR? | Senseair

Why NDIR? A non-dispersive 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.

Green Gas vs. CO2 – Which is Better? - Modern Airsoft

Nov 06, 2019· CO2 is going to kick harder, shoot faster, and work better in colder temperatures. Due to it’s higher pressure, a CO2 powered pistol will kick much harder than a green gas weapon. Also due to the pressure, most green gas pistols will have a higher FPS than their Green Gas counterparts. Finally, because of the self-contained cartridge design ...

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.
