There is software display export curves Plant Photosynthesis Meter Tester
Instrument introduction:
The HM-GH80 plant photosynthesis measurement system can measure the gas CO2 concentration, air temperature and humidity, leaf temperature, photosynthetic active radiation, intercellular CO2 concentration, gas flow and other elements, and calculate the photosynthetic rate, transpiration rate, stomatal conductance, cell Photosynthesis indicators such as the concentration of carbon dioxide and water use efficiency can also be used as a carbon dioxide recorder. FS-3080H plant photosynthesis measurement system adopts windows operating system and touch screen, which can display, save and export Pn curve, Tr curve, light-photosynthesis curve and humidity-transpiration curve. The scientific research of agronomy, forestry, ecology, and agrometeorology is widely used.
