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."@en ; sdo:inDefinedTermSet ; sdo:name "Vaisala GM70 atmospheric carbon dioxide analyser"@en ; sdo:termCode "SDN:L22::TOOL0229" .
