The LI7500A is LI-COR's open-path, high-speed, high-precision, nondispersive-infrared gas analyzer (IRGA). It accurately measures the in-situ densities of carbon dioxide and water vapor in turbulent air structures.

In an eddy-covariance application, the LI7500A is used in conjunction with a CSAT3 Sonic Anemometer to determine CO2 and H2O fluxes. The primary components of the LI7500 are the sensor head and the electronics enclosure.

The LI7500A, which replaces the LI7500, has added ports for other methods of data retrieval.
