This Compact Plant Water Status Console, comes complete with 5" vessel and G4 specimen holder and will operate with a pressure range up to 40 bar. It is equipped with a quick-connect coupling to the air supply bottle (you can select either the -V22 (22 cu.ft) tank or the -V33 (33 cu ft) tank which is included in the set). Ideal for field use because of its compact size (18.5" x 14.5" x 7") and watertight housing.
The 3115 Series Portable Plant Water Status Console provides a means of quickly and accurately measuring the water status of plant leaves.
|Weight:||26 lbs (11.8 kgs) (including tank)|
|Dimensions:||18.5 x 14.5 x 7 inches|
|Pressure Vessel:||1/2 litre (internal); stainless steel, 4 internal cam locks|
|Gauges:||Test Gauge, 4.5 in, white face, 0-20 bar (300 psi) or 0-40 bar (600 psi), accurate to within 1/4 of 1% full scale. Source Tank test gauge, 1.5 in, white face (0-3000 psi), part of the 3074 Quick Connect pressure supply hose assembly.|
|Valves:||Female, CGA 580 main valve on Compressed Gas Cylinder; Metering Valve to adjust the inflow pressurisation rate for uniform measurements; Three-Way Pressure Control Valve to pressurise or to exhaust gas in the pressure vessel.|
|Connecting Hose:||Stainless steel pressure hose with quick connect/disconnect at the PPW end and a male CGA 580 fitting on the compressed gas cylinder side|
|Pressure Tank:||Either 33 cu.ft. Compressed Gas Cylinder, 6.9” diameter x 15.8” length (shipped empty) or 22 cu.ft. Compressed Gas Cylinder, 5.25” diameter x 16.3” length (shipped empty)|
|Specimen Holder:||Accepts either sealing sleeves or sealing grommets for leaves or stems using 3015G4 Specimen Holder, or use sealing plugs with the 3015G2 Specimen Holder for blade-type leaves . Has a stainless steel sealing knob and aluminium closing ring, stainless steel camlock with safety relief piston (to prevent build up in the pressure chamber unless the specimen holder is cam-locked in proper position)|
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.
