| Definition | A gas concentration analyser that provides simultaneous, precise measurement of carbon dioxide (CO2) and methane (CH4) at parts-per-billion (ppb), and water (H2O) vapor at parts-per-million (ppm) sensitivity. Patented Picarro cavity ring-down spectroscopy (CRDS) technology enables an effective measurement path length up to 20 km in a compact cavity. Precision at 5 seconds and 5 minutes is 70 and 25 ppb for CO2; 0.5 and 0.22 ppb for CH4; and 80 and 30 ppm for H2O. Maximum drift at standard temperature and pressure (STP) over 24 hours is 120 ppb for CO2; 1 ppb for CH4; 100 ppm for H20. | |
