Infrared Gas Detectors Working Principle Instrumentation

Infrared Gas Detectors Working Principle Instrumentation

Mar 15, 2018The infrared (IR) Gas detection method is based on the absorption of infrared radiation at specific wavelengths as it passes through a volume of gas. Typically, two infrared light sources and one infrared light detector measure the intensity of two different wavelengths, one at the absorption wavelength and one outside the absorption wavelength. If a gas intervenes between the source …
