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-C_i response curves with the Rapid A-C_i 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.
