3000 Series Plant Water Status Consoles

In making a plant water status reading time is of the essence. Soilmoisture’s cam quick-cam-lock specimen holder and mating pressure vessel combination can’t be beat. These together with the variety of soft and easy-sealing grommets with a minimum twist-to-seal ratio, give you the fastest sealing time from tree, shrub or stock to the pressure vessel. Constucted for rugged use as a field stand or on the back of a pickup the unit is easy to handle and work with. Large accurate gauge and swivel allow for maximum readouts in almost any condition. These features combined with a large capacity tank will give you a lifetime of value.

The Plant Water Status Console, Model 3000F01, is supplied without the compressed gas cylinder or the pressure regulator, but does come with a 5-foot long, flexible, high pressure (3,000 psi working pressure) stainless steel connecting hose to connect to your pressure source. One end of the connecting hose is sealed to the pressure inlet of the console. The other end can be fitting with standard 1/4-inch pipe fittings to connect to your regulated pressure source. We recommend you use brass pipe and tube fittings that have a 3,000 psi working pressure. The regulated pressure that you supply to the console must not exceed the maximum pressure reading of the pressure readout gauge of the console. For standard units this pressure is 600 psi

Theory of operation 

The roots of a plant are using reverse osmotic forces to overcome the matrix potential of the soil.  The stomates on the leaves of a plant are transpiring at different rates throughout the day.  The resulting  tension in the xylem column can be measured using a plant water status console device. 
The petiole of a leaf or stem is placed in a rubber grommet so the leaves are inside the pressure chamber and the stem is outside at atmospheric pressure.  By pressurizing the chamber and watching the point where the sap oozes out of the stem at atmospheric pressure the 2 forces are in balance – the reading on the gauge and the tension in the xylem column.  This value can vary from the bottom to the top of the plant and at different times of the day due to temperature, humidity, sunlight, and wind.   By stressing the plant, better crops can be produced and water use better managed.
