Fabric Hydrostatic Pressure Tester
The Fabric Hydrostatic Pressure Tester is a laboratory instrument used to determine the resistance of textile fabrics to water penetration under increasing hydrostatic pressure. The instrument applies water pressure uniformly from below the specimen and detects the pressure at which water penetration occurs, providing reliable data for evaluating fabric water resistance.
Application
The Fabric Hydrostatic Pressure Tester is suitable for hydrostatic water resistance testing of the following materials:
Canvas and tightly woven fabrics
Oilcloth and coated fabrics
Tent fabrics and rainproof textiles
Clothing textiles requiring water resistance evaluation
The instrument is widely used in textile quality control laboratories, inspection institutions, and research facilities.

Test Procedures
Secure the fabric specimen in the clamping device with the test surface facing upward.
Select the required pressure increase rate and pressure unit according to the test standard.
Start the test; water pressure is applied uniformly from below the specimen.
Observe the specimen surface and record the pressure at which water droplets penetrate.
Stop the test automatically or manually after penetration is detected.
Maintenance Information
Clean the specimen clamping area and water circuit after each test.
Periodically inspect seals, O-rings, and tubing for wear or leakage.
Calibrate the pressure sensor regularly using the calibration plate.
Drain residual water from the system when the instrument is not in use for extended periods.
