LI-6800 Portable Photosynthesis System
The LI-6800 Portable Photosynthesis System is the major system for photosynthesis research
The LI-6800 Portable Photosynthesis System is the major system for photosynthesis research. Offering fast survey measurements of plants, response curves, algae measurements, and soil gas flux measurements, the LI-6800 advances research and education.

About LI-6800 Portable Photosynthesis System
Explore new frontiers with real-time leaf-level carbon isotope discrimination, and CH4 and N2O flux measurements.
Measuring gas exchange and fluorescence together shows not just how much photosynthesis is happening, but why—revealing how plants respond to stress, light, nutrients, or treatments in real time. This gives you a clearer way to quantify how factors like fertilizers, the environment, or genetics are impacting plant performance.
This means you can build a more complete picture of what's happening at the leaf and gain a stronger, more mechanistic understanding of plant physiology.
