G2311-f EC Flux Gas Concentration Analyzer
Measures CO2, CH4, and H2O
This product has been discontinued. Please refer to our Discontinued Products for information on replacement analyzers.
The Picarro G2311-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 G2311-f data sheet for precision and drift specifications in additional operating modes.
