Long Term Systems

Specifications:
CH₄/CO₂/H₂O Trace Gas Analyzer

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.

• Provides real-time flux data when connected to the LI-8250 Multiplexer
• Needs minimal field infrastructure for long-term, unattended measurements
• Requires low power (22 W)
• CH₄ Precision (1σ): 0.60 ppb at 2 ppm with 1 second averaging

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.

• Works with the LI-8250 Multiplexer for on-site fluxes and SoilFluxPro™ Software for simple post-processing
• Requires low power and minimal field infrastructure for long-term deployments
• N₂O Precision (1σ): 0.40 ppb at 330 ppb with 1 second averaging

LI-870 CO₂/H₂O Analyzer

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.

• Durable, weather resistant design features a user-serviceable optical bench
• Provides real-time CO₂ flux data when connected to the LI-8250 Multiplexer
• Low power requirements and powered directly by the LI-8250
• Accuracy: Within 1.5% of reading
• Measurement range: 0 to 20,000 ppm

If you are looking for a laser-based solution for soil CO₂ flux survey measurements, the LI-7815 CO₂/H₂O Trace Gas Analyzer is available. Ask us which solution is a good fit for your research.

Flexible options

Research based on your gas of interest. The LI-8250 Multiplexer integrates third-party analyzers to support fluxes of isotopologues and other gases. Third-party analyzer data is collected concurrently with chamber data and the two sets can be later merged with SoilFluxPro™ Software to calculate fluxes.*
