The LI-7500RS Open Path CO2/H2O Gas Analyzer is designed for high-speed CO2 and water vapor measurements in ambient air. Low power requirements and low maintenance make it ideal for field deployments.

Now Includes the SMARTFlux® System

The SMARTFlux System runs EddyPro® Software on a powerful microcomputer to compute final flux results as data are logged. No preliminary estimates. No legacy programming language. Just final, fully processed flux results. The same dependable results you get from EddyPro Software on a desktop computer, only computed in real time at the site.

SMARTFlux is ready to connect with FluxSuite™ Software —to put your results and system performance information online. In FluxSuite, you can view results, get email notifications, and check the performance of your instruments from computers and smartphones.
