The LI-7200 Enclosed CO2/H2O Analyzer is a high speed, high precision, non-dispersive infrared gas analyzer designed for applications that require fast and accurate CO2/H2O measurements. For eddy covariance applications, it mounts atop a flux tower or measurement platform and uses a short inlet tube co-located with the sample volume of the sonic anemometer.

The LI-7200 maximizes the strengths of traditional open path and closed path instruments. Open path analyzers feature excellent frequency response, low power requirements, tool-free optical cell cleaning, and are light weight. Closed path analyzers also provide many benefits, including low susceptibility to rain, fog or snow, and the potential for automated calibration. These features are brought together in the LI-7200, making it the first gas analyzer with the consistency of closed path instruments and the practicality and low power requirements of open path instruments.
