    Product introduction:
    Hly-EXGH2 can measure CO2 concentration, air temperature, leaf temperature, air humidity, leaf chamber humidity, photosynthetically active radiation intensity and other factors by open circuit measurement and closed circuit measurement, and calculate the photosynthetic rate, transpiration rate, intercellular CO2 concentration, stomatal conductance, water use efficiency and other indicators of plants. HLY-GH2 plant photosynthesis instrument has a wide application prospect in many professional experimental courses, such as biology, agronomy, horticulture, forestry, insects, microorganisms, animals and so on.


    1. Multi function: simultaneous determination of photosynthetic rate, transpiration rate, intercellular carbon dioxide concentration, stomatal conductance and water use efficiency, as well as carbon dioxide concentration, air humidity, leaf room humidity, photosynthetically active radiation, air temperature, leaf temperature and other indicators;           

    2. Intelligent: multi information Chinese menu display and cursor guided operation, real-time display and storage of measurement process and final results on screen;

    3. Easy to carry: small size, light weight, portable, single person operation.
