JC-FS80H Plant Photosynthesis Measurement System

1、 Product Introduction
The plant photosynthesis measurement system can measure factors such as gas CO2 concentration, air temperature and humidity, plant leaf temperature, photosynthetically active radiation, intercellular CO2 concentration, gas flow rate, etc., and calculate the four major photosynthetic indicators of plants, including photosynthesis (respiration) rate, transpiration rate, stomatal conductance, and water use efficiency. It can also be used as a standalone carbon dioxide recorder. The FS-3080H plant photosynthesis measurement system uses a Windows operating system and a touch screen display, which can display, save, and export CO2 photosynthesis curves, temperature photosynthesis curves, light photosynthesis curves, and carbon dioxide change curves. Widely applied scientific research in disciplines such as agriculture, forestry, ecology, and agricultural meteorology.
