Continuous Innovation in
Gas Exchange & Fluorescence
The LI-6400XT Portable Photosynthesis and Fluorescence System is the most referenced photosynthesis system worldwide in peer-reviewed literature. It has multiple advantages that make it the top choice for researchers.
Rapid Response: Gas analyzers are located in the sensor head, minimizing time delays.
Accurate and precise: Accurate to 1.5%; precision of ± 0.09% at 350 ppm CO2.
Portable: Laboratory-quality measurements in a field-portable system.
A variety of applications are supported by many chambers and light sources.
Open-source software provides an unprecedented level of automation and flexibility.
Powerful networking capabilities provide a variety of data output, file sharing, remote diagnostics and training possibilities.
Complete solution: Measures fluorescence and gas exchange simultaneously over the same leaf area with full control of environmental variables.
Reliable: LI-COR's commitment to continuous innovation and quality products (ISO 9001:2001 certified) ensures your LI-6400XT remains a smart choice for years to come.
Rugged: Can be used in environments ranging from the moist tropics to the dry arctic.
