| Definition | An instrument designed for the measurement of atmospheric carbon dioxide incorporating a probe that connects to a pump aspirator. The probe contains a CARBOCAP sensor comprising three major components - a light source, a Fabry-Perot interferometer and an IR detector. The interferometer allows light of two wavelengths to pass through to the detector - the wavelength at which carbon dioxide absorbs light and a nearby non-absorbing wavelength for comparison purposes. The probe is used in conjunction with a MI70 meter which promotes easy transfer of data to a PC. | ||
