Overview
Cometech QC-317F Digital Hydrostatic Head Tester (Hydro tester) evaluates the water penetration resistance of high-waterproof garments and coated fabrics by applying hydrostatic pressure and recording the penetration condition. It features an open-plan structure with a large observation space and built-in test lighting to help detect water drops on the specimen surface. A special pressure-control design helps keep pressurization speed stable across soft and hard specimens, and an automatic decompression system helps reduce water splashing when the specimen bursts.
