1. Purpose:

It can measure the water potential of whole leaves or branches of plants for daily water relationship measurement and irrigation table formulation.

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 like tissue.

3、 Characteristics:

The instrument comes with a comfortable shoulder strap and5 buckles, convenient for carrying and fixing on mechanical vehicles in the wild. Aluminum gas cylinder, secured to the portable case with a wide buckle strap for easy use and replacement,Can be conveniently used for field operations. Digital display dial.
