Portable photosynthesis analyzer

　　Brand of photosynthesis analyzer：

LD-GH80Brand of photosynthesis analyzerIt can measure factors such as gas CO2 concentration, air temperature and humidity, leaf temperature, photosynthetically active radiation, intercellular CO2 concentration, gas flow rate, etc., and calculate photosynthetic indicators such as plant photosynthetic rate, transpiration rate, stomatal conductance, intercellular carbon dioxide concentration, and water use efficiency. It can also be used as a standalone carbon dioxide recorder. The plant photosynthesis measurement system adopts a Windows operating system and a touch screen display, which can display, save, and export Pn curves, Tr curves, photosynthesis curves, and humidity transpiration curves. Widely applied scientific research in disciplines such as agriculture, forestry, ecology, and agricultural meteorology.

Product Features of LD-GH80 Plant Photosynthesis Measurement System:
