| Definition | A non-dispersive infrared gas analyser that measures carbon dioxide and water vapour concentrations in the atmosphere. The power received from the infrared source is measured at three wavelengths: one at a wavelength that is absorbed by carbon dioxide, another at a wavelength that is absorbed by water, and the third at a non-absorbing reference wavelength. The absorbance of each gas is calculated and converted to molar fraction using density, pressure and temperature data. |
