Hydrostatic Head Tester TF163C
Hydrostatic Head Tester, used for determining the resistance of fabrics (canvas, coated fabrics, cover cloth, rainproof clothing fabrics and geotextile materials) and films to water penetration under pressure while firmly clamped in the test rig of standard area.
Application
Hydrostatic Head Tester, used for determining the resistance of fabrics (canvas, coated fabrics, cover cloth, rainproof clothing fabrics and geotextile materials) and films to water penetration under pressure while firmly clamped in the test rig of standard area.
Specification
- Closed-loop controlled servo motor drives pistons to achieve the unique water pressure raising rate balance system.
- Variable test method can be selected, test time and variable pressure increasing rate can be set and saved.
- Wide range of pressure increasing rate and freely adjustable. Pressure increasing system is adjusted by the dynamic feedback to prevent overload.
- Real-time test results are shown on the large colourful touch panel and computer.
- Test results can be made up to a report on software and print out directly.
- 5 test methods are included
Pressure raising mode, Constant-pressure mode, Constant pressure & fixed time mode, Extending-relaxing mode, Water penetration and leakage mode. - Equipped with a LED lamp to observe test process clearly.
- Pressure Range
0 ~ 200kPa (20 m water column).
0~ 500kPa (50 m water column).
0 ~ 1000kPa (100 m water column). - Increasing rate of water pressure 0.1 ~ 100kPa/min stepless adjustable
- Units Pa, kPa, mmHg, cmH2O
- Automatic clamp with holding force 5kN
- Standarad Test Head 100cm2 (7.8cm2 optional)

What Criteria to Consider During Hydrostatic Testing？
1.Water temperature: water temperature directly affects the water pressure value. With higher water temperature, the measured water pressure is lower. Therefore, when testing similar products, you should choose the same water temperature.
2.The rate of water pressure rise: The current water pressure gauge typically has two rates; 10cm / minute, or 60cm / minute. The test should indicate which rate was used.
Readings: Different water pressure levels have different reading level margins for error: For 1m and below the margin for error in the water column is 0.5cm, for 1 ~ 2m, the margin is 1cm, and for 2m and above, the margin is 2cm.
3.Eliminating Bad Data:
a.No consideration for fine water drops that no longer increase after formation.
b.Consecutive water seeping in the same place of the fabric is not cumulative, it should only be counted as one drop of water.
c.If the third seepage occurs at the edge of the clamp frame and the water pressure measured at this time is lower than the lowest of the other samples in the sample, the data should be thrown out, and another sample/test should be taken.
Q: Is this machine to measure the water resistance / proofness of PU/PVC samples (Water column test)?
A: Yes, it is.
