Product Description

YG812E Textile Fabric Hydrostatic Pressure Head Tester is used to measure the water resistance of various fabrics (such as coated fabrics, tent fabrics, non-woven fabrics, membrane materials, rainproof clothing fabrics and geotextile materials, etc.) that have undergone waterproof treatment.

It complies with GB/T 4744、ISO811、AATCC 127、DIN 53886、JIS L 1092.


  • Touch screen control, English menu, man-machine dialogue mode, easy to operate.
  • The built-in thermal printer is convenient for quickly printing the test results on site.
  • The servo motor drive system is adopted, the water flow is controlled by a microcomputer, the pressurization rate range is wide and steplessly adjustable, and the pressurization speed is accurate.
  • Adopt high-precision pressure sensor, sensor automatic overload protection, pressure control adopts dynamic feedback adjustment, effectively prevent pressure overshoot.
  • Pneumatically clamp the sample, which is convenient and quick, so that the sample is evenly stressed and prevents the sample from being damaged.
  • Five test modes are optional, pressurization method, constant pressure timing method, constant pressure timing method, deflection relaxation and water seepage and leakage method.
  • Seven test units can be switched freely: Pa, kPa, mmHg, mmH2O, cmH2O, PSI, Bar.
  • The built-in professional LED lighting device is convenient for observing the water drops, and is equipped with a special water drop recording button, which can record the pressure results of the water drops for many times.
  • With the automatic identification of sample rupture during the experiment, stop and record the experimental value.
  • Instrument control mode: touch screen control and PC computer control are optional.
