EC flux and atmospheric monitoring for carbon dioxide (CO2), methane (CH4) and water (H2O)
Picarro G2311-f Analyzer
Measure CO2, CH4 and H2O in a single instrument at 10 Hz or 0.2 Hz for eddy covariance, gradient, eddy accumulation and other methodologies.
- Dry mol fractions reported automatically. No drying. No post-correcting
- Automatic synchronization with 10 Hz anemometer data in real time
- Parts-per-billion sensitivity, precision and accuracy with virtually no drift
- Rugged and insensitive to changes in ambient temperature in the field
Measuring localized fluxes of greenhouse gases for extended periods in challenging environments requires extreme precision and rock-solid reliability. For diverse applications from ecosystem respiration, to atmospheric science, to carbon cycle measurements and micrometeorology, Picarro's G2311-f is capable of measuring CO2, CH4 and water vapor in low flow, high-precision and in 10 Hz flux modes.
