Extend your soil gas flux measurements with a long-term system from LI-COR and get a complete picture of greenhouse gas fluxes in your soil. Connect up to 36 chambers with methane, nitrous oxide, or carbon dioxide isotope analyzers to evaluate greenhouse gas flux variation across a footprint of up to 2800 square meters.
All components are engineered and designed for field research. Deploy and leave your rugged, weatherized system unattended for long periods of time while it takes repeated, automated measurements in the field based on a configuration you can build in software customized for LI-COR systems.
With a long-term soil gas flux system, you can take automated measurements at many locations around your site over an extended period. Long-term, continuous datasets allow you to:
With a fully integrated system of LI-COR analyzers, hardware, and software, you can monitor real-time fluxes and isotopic composition in the field over weeks, months, or even years. With free, embedded software and an easy-to-use interface, you can view data fluxes directly on your smartphone, tablet, or laptop. Add a cellular modem and send daily summary files to monitor your site and know when you need to visit.
Researchers have entrusted their soil gas flux research to LI-COR products for more than 20 years, and more than 1,500 LI-COR Trace Gas Analyzers are taking measurements around the world. All system components are weather, splash, and dust resistant, designed to withstand the rigors of field research for entire seasons.
Chambers can make all the difference in obtaining reliable data. LI-COR long-term chambers are intended for extended field deployment and use a patented design to minimize artificial impacts on soil environment conditions.
Free, embedded software provided with all LI-COR long-term systems– SoilFluxPro™– is the single access point to manage, analyze, and visualize data from your long-term research site.
For incubation experiments, respirometry, and measurement of gas exchange from samples in flasks, our complete solution provides the same advantages in the lab as in the field.

The LI-7810 CH4/CO2/H2O Trace Gas Analyzer provides precise and stable methane measurements in a rugged and affordable water-resistant case. The LI-7810 combines patented technologies with Optical Feedback-Cavity Enhanced Absorption Spectroscopy (OF-CEAS) in one durable instrument for long-term field deployment.
The LI-7820 N2O/H2O Trace Gas Analyzer is a low power, laser-based analyzer for long-term measurements. With the same ease of use as other LI-COR trace gas analyzers, this highly precise N2O analyzer pairs easily with the LI-870 for added CO2 measurements or the LI-7810 for added CO2 and CH4 measurements.
The LI-7825 reports δ13C, δ17O, and δ18O with high precision and accuracy in a field-deployable, rugged, and portable design. Built on the same optical bench as its predecessors in the LI-COR Trace Gas Analyzer platform, the direct, real-time measurements from the LI-7825 allow researchers to identify sources and sinks of carbon in soil.
The LI-870 takes rapid and precise soil CO2 flux measurements. Designed for durability, a weatherproof case with weather, dust, and splash resistant components make the LI-870 suitable for long-term deployment in harsh conditions.
The 8200-104 Opaque Chamber uses a reflective white enamel chamber that rotates to and from the soil collar for automated measurements. This chamber is designed to be left in the field for long periods of time and can connect SDI-12 sensors for additional measurements at the chamber.
Specifically designed for net carbon exchange (NCE) research, the 8200-104C Clear Chamber allows plants within the collar to receive sunlight and continue photosynthesis. This chamber can be left in the field for extended periods and connects with SDI-12 sensors.
At the core of a LI-COR long-term soil gas flux system is the LI-8250 Multiplexer. The Multiplexer connects the analyzers and chambers at your soil gas flux research site.
Powered by the LI-8250 Multiplexer, each Extension Manifold allows multiple chambers to share a single 8250 port–extending the maximum number of chambers from 8 to 36.
Expanding your soil gas flux research to include CO2 isotope measurements has never been easier. The Calibration Manifold connects to the LI-7825 CO2 Isotope/NH3 Trace Gas Analyzer and the LI-8250 Multiplexer for trustworthy long-term carbon isotope measurements.
SoilFluxPro is a powerful, free software provided with all LI-COR long-term systems for management, analysis, and visualization of soil gas flux data.
