Advantages of the
Soil CO2 Flux System
The LI-8100A Automated Soil CO2 Flux System is used for collecting accurate and reliable soil flux data. Years of research and scientific expertise led to a unique design that addresses the critical considerations for making accurate soil CO2 flux measurements.

These critical considerations include:
Accounts for Altered Diffusion Gradient
Changes in the gradient lead
to inaccurate estimates of
Minimizes Environmental Disturbances
Accurate measurements require minimal disturbance to environmental, biological and physical conditions that have an impact on CO2 production and transport within the soil profile.Learn More
CO2 flux from soil is sensitive to the atmospheric pressure immediately above the soil. The measurement system should not change that pressure.Learn More
Provides Thorough Mixing
The CO2 concentration in the measured samples must be representative of the entire chamber. Poor mixing can lead to noisy and inaccurate flux data.Learn More
