G2311-f EC Flux Gas Concentration Analyzer
Measures CO2, CH4, and H2O
The Picarro G2301-f flux gas concentration analyzer provides simultaneous, precise measurement of carbon dioxide (CO2), methane (CH4), and water (H2O) vapor at 10 Hz for eddy covariance, gradient, and eddy accumulation methodologies. High-precision, low-drift operation makes it ideal for measuring localized fluxes over extended periods in agriculture and soil science, ecology, and emissions quantification applications.
- Simultaneous and continuous measurement of two or three (dual mode) atmospheric trace gases
- Automatic synchronization with 10 Hz anemometer data in real time
- Parts-per-billion sensitivity, precision, and accuracy with exceptionally low drift
- Water correction automatically reports dry gas mole fractions
Flux mode precision at 10 Hz is ≤200 ppb for CO2 and ≤3 ppb for CH4. Maximum drift at standard temperature and pressure (STP) over 24 hours is ≤250 ppb for CO2 and ≤2.5 ppb for CH4. Water correction software automatically reports dry gas mole fractions to help reduce research complexity and consumable costs. See the G2301 data sheet for precision and drift specifications in additional operating modes.
