The plant transpiration rate meter is used to quantitatively measure the influence of various factors on the stomatal behavior of leaves. It can conveniently, repeatedly, and accurately calculate the stomatal conductance and transpiration rate. It can also measure the air temperature and humidity, leaf surface temperature, and photosynthetically active radiation. Therefore, the measurement of the transpiration rate of plants is of great significance for agricultural scientific research, teaching, horticultural research, forestry research, etc.
Measurement Method
Closed-circuit measurement
Measurement Principle
Principle: According to the principle of cyclic diffusion, the measurement and calculation are carried out based on the change in the humidity of the space where the plant leaves are located.
Test Indicators
