NDIR Gas Sensors Electrical Optical Components, Inc.

Nondispersive Infrared Gas Detectors. 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.
