Advantages of the

LI-8100A Automated
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:

feature-2

Accounts for Altered Diffusion Gradient

Changes in the gradient lead
to inaccurate estimates of
the fluxes.

8100-feature1

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.

chamber-pressure-equilibrium

Equalizes Pressure

CO2 flux from soil is sensitive to the atmospheric pressure immediately above the soil. The measurement system should not change that pressure.

feature-4

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.
