Hydrostatic Head Tester | Reliable Waterproof Testing Solutions
Blog 2 12 月, 2025
The Hydrostatic Head Tester is a precision laboratory instrument designed to evaluate the water resistance of fabrics, coatings, and composite materials. By applying controlled hydrostatic pressure, this tester measures the fabric’s ability to withstand water penetration, providing critical data for textile, outdoor gear, and protective material manufacturers. Equipped with a programmable PLC control system and digital cycle counter, it delivers reliable and repeatable test results.
Applications
The Hydrostatic Head Tester is widely used for testing water-repellent fabrics, waterproof coatings, rainwear, tents, and other outdoor textile products. It is essential for quality control, research and development of new water-resistant materials, and compliance with international water resistance standards. The tester ensures that materials meet performance requirements for durability and water protection.
