Portable plant photosynthesis meter FK-GH30

Short Description:

Detailed Introduction:

The instrument can directly calculate photosynthesis indicators such as photosynthetic rate, transpiration rate, intercellular CO2 concentration, stomatal conductance, etc. of plants by measuring the amount of CO2 absorbed (released) by plant leaves within a certain period of time and simultaneously measuring air temperature and humidity, leaf temperature, light intensity and leaf area assimilating CO2.The instrument has the outstanding advantages of high sensitivity, rapid response, strong anti-interference, convenient operation, and can be used for in-vivo determination and continuous determination. Therefore, it is widely used in many fields such as plant physiology, plant biochemistry, ecological environment, agricultural science, etc.
