In a measurement of quantum efficiency of photosynthesis in green plants it was found that 10 counter of red light of wavelength 6850 and stamps needed to release 1 molecules of o2 the average energy storage in this process for one mole o2 evolved in one 12 o'clock kelvin

- Fast control loops
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.
H2O control
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.
Rapid temperature control
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.
High flow rates
User-adjustable flow rates—from 0 to 2.5 liters per minute—minimize response times and expand the system versatility.
precise contgrol allows for faster measurements
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.).
Gas input port
A gas input port enables you to subject the leaf to custom gas blends.
actual leaf temperature
A unique, durable fine-wire thermocouple maintains direct contact with the leaf—to get the actual leaf temperature with every measurement.
Leaf area
- 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
