Photosynthesis measuring instrument is an experimental instrument for testing the photosynthesis of living leaves of plants in artificial climate chambers, greenhouses, greenhouses, fields, etc. The measurement content includes air CO2 concentration, ambient temperature and humidity, leaf room temperature humidity, leaf surface temperature, atmosphere Pressure, photosynthetically active radiation (PAR), leaf photosynthetic rate (Pn), stomatal conductance (Gs), leaf transpiration rate (Tr), intercellular CO2 concentration (Ci), water utilization efficiency (WUE), respiration rate (Rd) , Transpiration Ratio (TR), a total of 15 parameters, which can be used for scientific research such as plant growth physiology, photosynthetic physiology, stress physiology research, etc. The plant photosynthesis meter is suitable for agricultural scientific research, teaching, horticulture, grass industry, forestry and a wider range of fields.
Features:
•Intelligent: Using Android operating system and highly sensitive touch screen. Efficient human-computer interaction, real-time display of the measurement process, and better operating experience;
•High stability: Dual-wavelength infrared carbon dioxide analyzer, adding temperature adjustment and atmospheric pressure measurement units, effectively improves the stability and accuracy of carbon dioxide. Effectively avoids the disadvantages of excessive fluctuations in carbon dioxide values due to temperature changes;
•Multi-function: 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 active radiation, air temperature, leaf temperature, atmospheric pressure and other indicators;
•Large screen: 7-inch high-sensitivity touch screen, humanized operation interface, providing users with better data display.
•Data export: Supports U disk copying of data, eliminating the need for driver plug-in and removal.
•Long battery life: It can be used continuously in the field for 10-12 hours when fully charged.
•Convenience: small size, light weight, portable with suitcase, convenient for single-person mobile testing;
