- Definition technique for measuring the volumetric concentration of carbon oxides in a gas sample, by shining an infra-red beam through a sample cell (containing CO or CO2, and measuring the amount of infra-red absorbed by the sample at the set wavelength Reference "COM-EN, based on:Cambustion > Operating Principle. http://www.cambustion.com/products/ndir500/operating-principle [2.2.2015]"
- Comment NDIR measurement is based on the principle that each constituent gas in a sample will absorb some infra red at a particular frequency.
