The G018P Hydrostatic Pressure Tester is an upgraded version of the G018. designed to measure the hydrostatic resistance of materials. In a standard atmospheric environment, the instrument determines the pressure at which water first appears on the non-contact side of the sample under continuously increasing water pressure. This provides a precise assessment of the material’s waterproof and water vapor resistance properties.
Application
Testing woven, laminated, and coated fabrics for water resistance and breathability.
Evaluating high-density fabrics, canvas, felt, oilcloth, tent materials, and impermeable fabrics.
Quality assessment for outdoor apparel, umbrellas, rain gear, and protective clothing.
Medical and chemical protective garments testing for body fluid and chemical liquid penetration resistance.
Nonwoven/filtered fabrics, breathable waterproof fabrics, and paper/board water permeability tests.
