The LI-600 and LI-600N are designed to make high-quality leaf-level measurements simple, portable, and efficient. Both instruments are built for rapid measurements in the field, greenhouse, and lab under ambient conditions.
Simply use a workflow that supports consistent data collection across users and experiments—no complex setup or advanced training required.
When measurements are fast and easy to collect, your experiments can expand. The LI-600 enables you to measure more plants, more treatments, and under more conditions—helping you capture meaningful variation across your study.
By measuring stomatal conductance and chlorophyll fluorescence together in one device, you can better understand how your plants regulate water loss, respond to light, or adapt to stress.
The LI-600 is designed to reduce setup time and simplify measurements—so you can focus on collecting data, not on training yourself or your team.
Fast Measurements
Collect data from your plants in seconds, screening hundreds (or even thousands) of leaves per day
Portable Design
Take this handheld device anywhere you need it, no heavy or complex system required
Easy to Use
Get started in no time, thanks to an intuitive workflow that anyone on your team can learn and use
Gather key physiological data that helps you better understand plant performance. These measurements provide practical insight into how plants respond to their environment—so you can make more informed decisions in research, breeding, and other applications.
The LI-600 and LI-6800 Portable Photosynthesis System complement each other as part of a complete research workflow. Use the LI-600 to first screen large populations and identify meaningful differences in plant performance. Then use the LI-6800 to investigate those differences in detail under controlled conditions.

Rapidly screen up to 200 samples in an hour under ambient conditions with the LI-600.
Identify plants that stand out from the rest, whether it is improved water use, stress response, health, or other factors.
Measure detailed parameters under controlled conditions with the LI-6800 to understand what drives those differences.
Use both datasets to determine optimal conditions, treatments, plant types, and more.
