When you change the leaf chamber environment—light, temperature, CO2, or H2O—the instrument adjusts to the new setpoint right away thanks to Rapid Sensing™ Technology. The fast adjustment saves time and enables you to measure a plant’s response to rapidly changing conditions.
Providing full control over water vapor, the LI-6800 can maintain humidity at any level below condensing conditions in the leaf chamber and gas analyzers.
Capable of achieving 10°C below and above ambient temperature, the LI-6800 provides fast and precise temperature control. It can control temperature at a setpoint, track the ambient temperature, or ramp the temperature up or down according to your experimental requirements.
User-adjustable flow rates—from 0 to 2.5 liters per minute—minimize response times and expand the system versatility.
The precise control of CO2 allows for faster measurements, so you can perform rapid A-Ci response curves with the Rapid A-Ci Response (RACiR™) Method (Pat. Pend.).
A gas input port enables you to subject the leaf to custom gas blends.
A unique, durable fine-wire thermocouple maintains direct contact with the leaf—to get the actual leaf temperature with every measurement.
To fill the chamber area—and easily calculate leaf area—swap in one of several interchangeable inserts for different leaf area apertures on the Clear-top chamber and on the Multiphase Flash fluorometer.

A new chamber for measuring soil CO2 flux that uses technology from the LI-8100A Automated Soil Gas Flux System, and a new conifer chamber kit that expands the chamber volume, add to the long list of potential LI-6800 applications.
A paper with the LI-6800 Portable Photosynthesis System has just been published in Plant and Cell Physiology. This publication explores how the color of actinic light affects the estimate of the electron transport rate (ETR) when calculated from fluorescence measurements.
New options for leaf area let you fill the leaf chamber area—and avoid calculating leaf area—with interchangeable apertures. For bigger leaves, the new Large Leaf and Needle chamber has a 6x6 cm leaf area aperture.
The LI-6800 can complete a survey measurement in under a minute, with batteries that last all day. A large touchscreen display shows informative, full color plots that help you track the progress of each measurement. On-screen messages alert you to issues so you can collect consistent, high quality data.
The LI-6800 is fast and dependable. It is ready to collect incredible data wherever your research takes you.

“The LI‑6400 is a great machine, but all the little tweaks you made to the LI‑6800 improved the usability of it. The speed is great.”
