Automatic Hydrostatic Head Tester G-AH480


An Automatic Hydrostatic Head Tester is a testing instrument used to determine the water penetration resistance of fabrics, membranes, and waterproof materials. It applies gradually increasing water pressure to a specimen until water penetrates through the material surface, and automatically records the pressure value at the point of penetration to evaluate the material’s waterproof performance. The equipment features a high degree of automation, high testing accuracy, and excellent repeatability. It is widely used for performance testing of protective clothing, outdoor fabrics, and technical textiles.

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.
