The 3005 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.

Model 3005 is supplied with a pressurized gas tank, making it suitable for portable, field use. A hardwood sample preparation board is mounted to the heavy-duty aluminum chassis. 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.

Plant Water Status Console, with air supply. Must include 1 each of options A, B, C, and D. The most common configuration, 3005-1412, has a 7" high Pressure Vessel, 3015G4 Specimen Holder, 0 to 40 bar range, and set of 8" legs.
