Leaf Area Options for the LI-6800

Leaf Area Options for the LI-6800

New leaf area options for the LI-6800 Portable Photosynthesis System are available. Measurable leaf areas ranging from 2 cm2 all the way to 36 cm2 mean you can take measurements on leaves of nearly any shape and size.

An accurate measure of leaf area is an important parameter for calculating assimilation rate. If the area of the chamber occupied by the leaf completely covers the aperture, the leaf area calculation is simple — for example, with the 3×3 cm aperture, the measurable…

Using a Longer Cable for the External Quantum Sensor on the LI-6800

Using a Longer Cable for the External Quantum Sensor on the LI-6800

The standard external quantum sensor (LI-190R) provided with the LI-6800 sensor head (LI-6850) has a 12 inch (30.5 cm) cable terminated with a 3.5 mm audio plug.  For some applications, it may be desirable to place an external quantum sensor at a greater distance from the sensor head. For these applications, an audio plug adapter can be used in conjunction with another LI-190R quantum sensor with a longer cable. LI-190R sensors are available in cable lengths of 2m, 5m, 15m…
