1. Purpose:
It can measure the water potential of entire leaves or branches of plants, with a high range, and can be used for measuring the water potential of high water potential plants (such as plants in deserts and arid areas), as well as for daily water relationship measurement and irrigation table formulation. It can also be used with an air hole simulator. One machine can be used for two purposes.

2、 Principle:
The instrument leaves or branches are clamped in the sample chamber and pressurized with gas to observe the pressure at which the first drop of tissue fluid seeps out. The pressure value at this time is the water potential value of the plant sample tissue.
3、 Characteristics:
With the combination of portable high-pressure gas cylinders, it can be conveniently used for field operations. High range, suitable for research use. Digital meter reading makes it easier to view results.
At the same time, it can simulate the phenomenon of air pockets.
4、 Composition:
withHigh pressure sealing pipe system with 1/4 inch sealing gasket; 5 high-pressure sealing pipe gaskets; 1 solid standard rubber gasket; O-ring lubricant; 6-foot inflatable hose; Technical manual; Valve adjustment tool. And a complete set of accessories for the air pocket part.
