★Customization: Users can customize and edit experimental notes according to measurement needs, and can display Pn curve, Tr curve, light-photosynthesis curve and humidity-transpiration curve;

Data analysis: After the experiment is completed, multiple sets of data can be analyzed at the same time to generate curves with different colors, which is convenient for experimental data comparison;

★Large screen: 10-inch high-sensitivity touch screen, humanized operation interface, to provide users with better data display.

★Data export: Support wifi and Bluetooth transmission, data can be uploaded wirelessly; also supports USB copy data, free driver plug-in and unplug.

★Configure cloud platform: The test results can be transmitted to the platform selectively or in batches wirelessly, which is convenient for users to conduct long-term data management and visual analysis. Assist scientific research.

Long battery life: It can be used continuously in the field for 10-12 hours when fully charged.

Convenience: Small size, light weight, and can be carried with a suitcase, which is convenient for single-person mobile testing.

★Configure bracket: Convenient for long-term unattended testing, the host bracket height is adjustable, and the height and angle of the detection handle tripod are adjustable.
