The LI-7500A is a high speed, high precision, non-dispersive infrared gas analyzer that accurately measures densities of carbon dioxide and water vapor in-situ. With the eddy covariance technique, these data are used in conjunction with sonic anemometer wind speed to determine the fluxes of CO2 and H2O into and out of ecosystems.

The 6400-01 CO2 Injector System consists of an electronic controller, a CO2 Source Assembly that uses mini-cartridges for portable operation, and a CO2 tank fitting for greenhouse or laboratory operation. ……

The 6400-02B is designed for easy field operation. Mounting is as simple as replacing the upper half of the standard leaf chamber with the light source. The 6400-02B LED Light Source is totally integrated with the hardware and software of the LI-6400 Portable Photosynthesis System, providing maximum ease-of-use and application flexibility.

The 6400-09, in conjunction with the LI-6400, provides maximum operational convenience and addresses the important difficulties for soil CO2 flux measurements. The key to the 6400-09 chamber design is having the infrared gas analyzers in the LI-6400 sensor head.

The 6400-22L is the newest addition to the long line of leaf chambers and accessories available for use with the LI-6400/LI-6400XT Portable Photosynthesis System.

The 6400-40 Leaf Chamber Fluorometer transforms the LI-6400 System into the most integrated and powerful Portable Fluorescence and Gas Exchange System available.

The new 6400-70 AC Module allows the LI-6400 to be powered from mains power. It consists of a transformer and a separate battery-shaped unit that fits in the LI-6400 console. When used with a battery, the 6400-70 will trickle charge the battery, which also provides for continued operation in the event of a mains power failure.
