The LI-7500DS is designed for high-speed CO2 and water vapor measurements in ambient air. Lower power and maintenance requirements make it ideal for field deployments.
Requiring only 4 watts during normal operation, the LI-7500DS features lower power demands than any other EC gas analyzer available. It is ideal for deployment in remote areas where power is limited.
Omnidirectional sampling provides versatile installation options and continuous data coverage.
Logs complete eddy covariance data sets—including wind speed measurements from a sonic anemometer and supporting meteorological, radiation, and soil data from a LI-COR Biomet System.
Now includes the SmartFlux®System
The SmartFlux®System runs EddyPro®Software on a powerful microcomputer to compute final flux results as data are logged. It delivers 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 eddy covariance system online. In FluxSuite, you can view results, get email notifications, and check the performance of your instruments from a computer and smartphone.
The LI-7500DS instrument
Miniaturized electronics and simplified hardware make the LI-7500DS easier to use. This compact instrument delivers high-speed measurements and precision needed for flux measurements. Designed for long-term deployment, the LI-7500DS improves upon a proven platform.
1
Ambient air temperature measurements at the optical path.
2
Temperature controlled optics and detector provide stable measurements—even in wide temperature fluctuations.
3
Precision optical components reduce sensitivity to contamination in dusty environments.
4
Scratch-resistant sapphire lenses for simple cleaning in the field.
5
High-performance brushless chopper motor provides dependable long-term operation.
How it works
The LI-7500DS uses non-dispersive infrared spectroscopy to measure CO2 and water vapor densities in air.
Infrared radiation is transmitted through temperature-controlled optical filters, then through the open sample path to a thermally regulated lead selenide detector. Some of the infrared radiation is absorbed by CO2 and water vapor in the sample path. Gas densities are computed from the ratio of absorbed radiation to a reference.
