The 3000 Series Plant Water Status Console provides a means of quickly and accurately measuring the water status of plant leaves. A leaf or small branch is placed in the sample chamber with the cut end protruding from the specimen holder. Pressure is built up inside the chamber until the pressure exceeds the tension inside the plant material, and xylem sap begins to flow from the cut end. The tension can then be read directly from the pressure gauge. The model 3000 must be connected to an external source such as a compressed gas cylinder. Sample chambers are available in several different lengths, ranging from 7" (18 cm) to 20" (51 cm). Two operating pressure ranges, 0 to 40 bars and 0 to 80 bars, are available. Two specimen holders are available, one for use with round-stem materials, and one for blade-type plant materials. A number of differently sized and shaped sealing sleeves and grommets assure that the plant material of interest is safely sealed in the specimen holder, allowing measurements to be made.
