Photosynthesis

The LI-6400 was the first photosynthesis measurement system to put the CO2 and H2O gas analyzers in the sensor head. These dual path, non-dispersive infrared analyzers feature an open path design with the optical bench of the sample analyzer open directly to the leaf chamber mixing volume. Leaf dynamics are measured in real time, preventing confounding correlations between gas exchange and changes in environmental driving variables.

Fluorescence

The field-installable Leaf Chamber Fluorometer easily attaches to the LI-6400XT sensor head. This integrated system gives the user complete control of the leaf environment for simultaneous collection of gas exchange and chlorophyll fluorescence data from a single, portable unit.

Soil Respiration

Attach the Soil CO2 Flux Chamber to the LI-6400XT System for an additional carbon cycle application. A pre-defined software protocol and automated measurement cycling ensure ease of use and accurate data collection.
