Photosynthesis measuring instrument

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;
