"A gas concentration analyser that provides simultaneous, precise measurement of carbon monoxide (CO), carbon dioxide (CO2), methane (CH4) at parts-per-billion (ppb), and water (H2O) vapor at parts-per-million (ppm) sensitivity. Precision at 5 seconds, 5 minutes, and 60 minutes is 15, 1.5, and 1 ppb for CO; 50, 20, and 10 ppb for CO2; and 1, 0.5, and 0.3 ppb for CH4. Maximum drift at standard temperature and pressure (STP) over 24 hours is 10 ppb for CO; 100 ppb for CO2; and 1 ppb for CH4. Water correction software automatically reports dry gas mole fractions."@en . . . . . .
