The CS7500 is an open-path, high-speed, high-precision, nondispersive infrared gas analyzer (IRGA) that accurately measures the in-situ densities of carbon dioxide and water vapor in turbulent air structures.
In an eddy-covariance application, the CS7500 is used in conjunction with a CSAT3 Sonic Anemometer to determine CO2 and H2O fluxes. The primary components of the CS7500 are the sensor head and electronics enclosure.
