Introduction to Gas Sensing Using Non-Dispersive Infrared ...

Non-dispersive infrared (NDIR) is a physical sensing technique that provides a number of advantages over catalytic gas sensing method. The main feature of this technique is that fixed narrow-band filters are utilized with separate IR detectors to detect a few gas absorption lines across a restricted wavelength range. This helps in eliminating the dispersive potion of a gas spectrometer. The ...
