The LI-8100A Automated Soil CO2 Flux System provides researchers sophisticated flux monitoring instrumentation in a dedicated system that is modular and easy to use. The System offers options of two short-term survey and two long-term chambers, in addition to the ability to multiplex up to 16 long-term chambers. LI-COR's research in this area has resulted in better comprehension of soil CO2 flux measurement problems and system design requirements.
Production of CO2 in the soil is primarily a function of respiration of roots and organisms in the soil and is influenced by environmental factors (soil temperature, soil moisture, etc.) and biological factors (above ground canopy size and growth, etc.). Soil CO2 efflux is a physical process driven primarily by the CO2 concentration diffusion gradient between the upper soil layers and the atmosphere near the soil surface. The measurement challenge is to provide a tool which causes minimal disturbance to environmental conditions that have an impact on CO2 production and transport within the soil profile and can be used across a wide range of environmental conditions. The LI-COR LI-8100A Soil CO2 Flux System was designed to meet these challenges.
Designed to minimize changes to the soil and environment that can affect the natural soil CO2 production and diffusion processes.
New patent-pending pressure vent design minimizes pressure pulses at chamber closing and allows pressure inside the chamber to track the ambient pressure even under windy conditions.
Both survey and long-term chambers close automatically, eliminating variations caused by manual chamber placement.
CO2 flux is calculated at the CO2 concentration of the surrounding ambient air. This minimizes effects resulting from the necessary increase in chamber CO2 concentration during a measurement.
Chamber geometry facilitates mixing without using fans, thus eliminating potential for chamber pressure perturbation.
Data analysis software is a powerful tool for viewing and quality control of data.
Measure in high CO2 environments up to 20000 ppm.
Wireless communications and LAN connectivity enabled.
