1Purpose:

Measure the water potential of fleshy, herbaceous, and woody plant leaves or branches.

IIPrinciple:

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.

IIIform:

(1) Main part of pressure chamber

1. Sample clamp: used to clamp measuring leaves or branches

2. Pressure chamber: diameter 7cm，13.5cmDeep brass pressure resistant tank

3. Pressure reading gauge: pressure sensor, digital LED display

4. Pressure regulating valve: High pressure gas inflation and deflation

5. High pressure connecting hose: connects the pressure sample chamber to the high-pressure gas source

6. Sample clip attachment: used for sealing samples, with two specifications: round hole and narrow hole

(II) High pressure gas supply section

1. High pressure gas cylinder: There are two volume specifications of 3L and 12.4L gas cylinders

2. High pressure gas regulator interface: Connect high-pressure pipelines or gas cylinders to detect and regulate gas output.

4Optional spare parts:

1. High pressure connecting hose: connects the pressure sample chamber to the high-pressure gas source

2. Sample chamber volume reducer: pressure resistant pad, used to save gas usage

3. Silicone oil: maintain instrument related connections to reduce wear and tear

4. O-type gasket: sample clamp and sample chamber sealing gasket

5. PP3 rechargeable battery and charger: used to support LED display

5Basic technical indicators:

1. Pressure measurement range: 0-40, 0-50, 0-80Bar

2. Resolution: 0.01Bar（1KPascal）

3. Pressure chamber size: 70mm × 135mm, 0.54L

4. Display: 12.7mm high LCD screen

5. Power supply: 9V alkaline PP3 battery

6. Pressure chamber host weight: 9Kg

7. Pressure chamber volume: 0.54L

8. Size specifications: 317mm × 254mm × 152mm

9. Weight: The host weighs 9kg, and the 3L gas cylinder weighs 5kg
