Photosynthesis Tester IN-GH3

Photosynthesis Tester

         The GH3 Plant Photosynthesis Tester is a laboratory instrument for detecting photosynthesis in living leaves of plants in artificial climate chambers, greenhouses, greenhouses, fields, etc. It can measure air CO2 concentration, ambient temperature and humidity, leaf chamber temperature and humidity, leaf temperature, atmospheric pressure, photosynthetically active radiation (PAR), leaf photosynthesis rate (Pn), stomatal conductance (Gs), leaf transpiration rate (Tr), intercellular CO2 concentration (Ci), water utilisation rate (WUE), respiration rate (Rd), transpiration ratio (TR), and water consumption rate (Ci), respiration rate (Rd), respiration rate (Rd), transpiration ratio (TR), and water consumption rate (Rd). CO2 concentration (Ci), water utilisation (WUE), respiration rate (Rd), transpiration ratio (TR), a total of 15 parameters, can be used for plant growth physiology, photosynthetic physiology, stress physiological research and other scientific research, plant photosynthesis tester for agricultural research, teaching, horticulture, horticulture, forestry and wider fields.

Product Features:

★Intelligent: adopts Android operating system, high sensitive touch screen. Efficient human-computer interaction, real-time display of the measurement process, better operating experience;

High stability: dual-wavelength infrared carbon dioxide analyser, adding temperature regulation and atmospheric pressure measurement unit, effectively improving the stability and accuracy of carbon dioxide. It effectively avoids the disadvantage of excessive fluctuation of carbon dioxide value caused by temperature change;

★Multifunctionality: Simultaneously measure photosynthesis 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, leaf temperature, atmospheric pressure and other indicators;

★Customisation: Users can custom edit the experimental remarks according to the measurement needs and display Pn curve, Tr curve, light-photosynthesis curve and humidity-transpiration curve;

-Data analysis: After the test is completed, multiple sets of data can be analysed simultaneously, generating curve graphs with different colours, which is convenient for comparison of experimental data;

★Large screen: 10-inch high-sensitivity touch screen, user-friendly operation interface, to provide users with better data display.

★Data export: support wifi, data can be uploaded wirelessly; at the same time support the U disk copy data, driver-free plug.

★Configuration cloud platform: test results can be selectively or batch wireless transmission to the platform, convenient for users to carry out long-term data management and visual analysis. Assist scientific research.

-Long battery life: can be used continuously for 10-12 hours in the field under full charge.

-Convenience: small size, light weight, with suitcase to carry around, convenient for single person mobile test.

★Configuration bracket: convenient for a long time unattended testing, the host bracket height adjustable, test handle tripod height angle are adjustable.
