Cavity Ring Down Spectroscopy Analyzer for Fast Flux Measurements of Carbon Methane and Water in Air

Fast CO₂ / CH₄ / H₂O Analyzer for EC Flux and Atmospheric monitoring - G2311-f

• Simplest configuration: Plug and Sync 10 Hz anemometer data in real time
• Highest precision CO₂, CH_{4 &} H₂O measurements at 10 Hz or 0.2 Hz
• Lowest Drift.  Stop unnecessary calibrations and reference gas measurements.
• Dry mol fractions reported automatically.  No drying. No post-correcting.

Measuring localized fluxes of greenhouse gases for extended periods in challenging environments requires extreme precision and rock-solid reliability. For diverse applications including ecosystem respiration to atmospheric science to carbon cycling to micrometeorology, Picarro's Cavity Ring-Down Spectroscopy (CRDS) technology is capable of measuring CO₂, CH₄ and water vapor down to parts-per-billion (ppb) sensitivity in both high-precision and fast, 10 Hz mode. In flux mode, the analyzer measures and reports the concentration of all three species at 10 Hz. 

The Picarro G2311-f Fast Analyzer reduces research complexity and helps to decrease potential errors by including three key features: extremely precise water vapor measurements with low- drift for accurate latent heat calculation; automatic time-sync and integration of anemometer data through the analyzer’s serial port to reduce clock drift errors and simplify data analysis; and automatic calculation & reporting of dry gas mol fractions to reduce analysis complexity and lower consumable costs. In addition, Picarro's CRDS technology features extremely low drift and high linearity with no optical maintenance and few moving parts. This reliability and minimized mechanical complexity ensure maximum measurement up time. In additional, all Picarro analyzers are subject to extensive drop and vibration testing at the factory before shipment as part of Picarro's best-in-industry quality assurance process.
