FS-3080H plant photosynthetic measurement system can measure gas CO2 concentration, air temperature and humidity, plant leaf temperature, photosynthetically active radiation, intercellular CO2 concentration, gas flow and other factors, and calculate plant photosynthetic (breathing) rate, transpiration rate, stomata The four photosynthesis indicators of conductance and water use efficiency can also be used alone as a carbon dioxide recorder. FS-3080H plant photosynthetic measurement system adopts windows operating system and touch display screen to display, save and export CO2-photosynthetic curve, temperature-photosynthetic curve and illumination-photosynthetic curve and carbon dioxide curve. Scientific research in agronomy, forestry, ecology, agrometeorology and other disciplines is widely used.
High stability: The newly developed dual-wavelength infrared carbon dioxide analyzer of this instrument company adds temperature regulation and atmospheric pressure measurement unit, which effectively improves the stability and accuracy of carbon dioxide. Effectively avoiding the disadvantages of excessive fluctuations in carbon dioxide values due to temperature changes;
Multi-functional: Simultaneous determination of photosynthetic rate, transpiration rate, intercellular carbon dioxide concentration, stomatal conductance and water use efficiency, as well as carbon dioxide concentration, relative humidity, photosynthetically active radiation and air temperature, blade temperature, atmospheric pressure and other indicators;
Intelligent: use the windows operating system, touch the display. The multi-information Chinese menu display and text guiding operation instantly display and store the measurement process and the final result screen. And can display CO2-photosynthetic curve, temperature-photosynthetic curve and illumination-photosynthetic curve;
Data analysis: Carbon dioxide difference and humidity are instantly displayed and saved, and equipped with special computer analysis software. After the test is completed, multiple sets of data can be analyzed at the same time to generate graphs with different colors to facilitate comparison of experimental data.
