Steaming rate measurement instrument

Use

The HM-ZT20 plant transpiration rate measurement meter is a scientific research plant air hole meter measured by opening. It is used to measure the effects of various factors on the cavity behavior of the blades. It can be convenient, repeated, and accurately calculated to calculate stomach impedance, pores guidance and steam rate. It can also measure air temperature humidity, leaf temperature, and photosynthetic radiation. Water and physiological research is widely used in plant leaves, research on crop water utilization, water coercion hazards, and biological control effects.
