- Measures small density changes at high speeds and over a wide range of CO2 and H2O concentrations.
- Provides high frequency response and minimizes airflow disturbance near the inlet with a specially designed inlet cap and intake tube.
- High stability under large ambient temperature variations with temperature-regulated optical filters and detector.
- Simplifies and improves flux calculations by computing dry mole fraction of CO2 and water vapor using fast temperature and pressure measurements of air in the sample cell.
- Reduces data gaps with continuous measurements through rain, snow, and fog.
- Logs complete eddy covariance datasets and computes flux results in real time with the SMARTFlux system (optional).
