Photosynthesis analyzer FK-GH30

Characteristics of photosynthesis analyzer FK-GH30:

By measuring the amount of CO2 absorbed (released) by plant leaves over a certain period of time, and simultaneously measuring factors such as air temperature and humidity, leaf temperature, light intensity, and leaf area for CO2 assimilation, the photosynthetic rate, transpiration rate, intercellular CO2 concentration, and stomatal conductance of plants can be directly calculated. This instrument has outstanding advantages such as high sensitivity, rapid response, strong anti-interference ability, easy operation, and the ability to perform live and continuous measurements. Therefore, it is widely used in many fields such as plant physiology, plant biochemistry, ecological environment, and agricultural science.
