Operating environment: temperature -20ºC-60ºC, relative humidity: 0-85% (no moisture condensation)
Power supply: large-capacity DC8.4V rechargeable lithium battery, which can work continuously for 12 hours on a single charge(without connecting an external light source)Product Features Of HM-GH80 Plant Photosynthesis Measurement System:High stability:
The dual-wavelength infrared carbon dioxide analyzer newly developed by the instrument company, with the addition of temperature adjustment and atmospheric pressure measurement units, effectively improves the stability and accuracy of carbon dioxide. Effectively avoid the disadvantages of excessive fluctuation of carbon dioxide value due to temperature changes;Multifunctional:
Simultaneously measure photosynthetic rate, transpiration rate, intercellular carbon dioxide concentration,
stomatal conductance and water use efficiency, as well as carbon dioxide concentration, relative humidity, photosynthetically
effective radiation and air temperature, leaf temperature, atmospheric pressure and other indicators;Intelligent:
use windows operating system, touch screen. Multi-information Chinese menu display and text-guided operation caninstantly display and store the measurement process and final results on the screen. It can also display Pn curve, Tr curve,light-photosynthesis curve and humidity-transpiration curve;Self-programming:
different light intensity, light stabilization time and measurement time under different light can be set
according to experimental needsA complete light-photosynthetic curve can be drawn.Data analysis:
After the test is completed, multiple sets of data can be analyzed at the same time to generate curves with
different colors to facilitate the comparison of experimental data;Convenience:
small size, light weight, portable, single operation;Optional Accessories For HM-GH80 Photosynthesis Analyzer:
