Professional Technology

The tester features a 10-inch color capacitive touch screen with multi-point touch and an Android 7.0 operating system. Users can easily control tests, save results in Excel format, and send them instantly via Wi-Fi.

Its simple yet efficient fixture design provides superior gripping force, ensuring that water does not leak from the sides. In addition, high-precision pressure sensors combined with advanced pressure control guarantee accurate results.

The instrument also includes an LED soft illumination system with digitally adjustable lighting. Moreover, the user-friendly software supports multiple test standards and offers convenient configuration.

For demanding applications, the pneumatic clamp head delivers strong clamping power, with a maximum pressure of four tons. As a result, users benefit from consistent, reliable, and precise testing performance.

Testing Standards

Test Principle

One surface of the test specimen is subjected to a hydrostatic pressure, increasing at a constant rate, until three points of leakage appear on its other surface. The water may be applied from above or below the test specimen.

The instrument contains a high precision pressure control system, which produces the test pressure in an internal water tank.

Application

Measurement the resistance of plastic foils, coated and uncoated fabrics, and non-woven to water penetration by means of the dynamic test method, the static test method, and the program test method.
