Hydrostatic Pressure Tester


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.

FAQ

(1) What is this product?

It is a hydrostatic pressure tester that measures the resistance of materials to water penetration.

(2) What is this product used for?

It evaluates waterproof, breathable, and fluid penetration resistance for fabrics, nonwovens, protective clothing, and paper materials.

(3) What is the working principle of this product?

The device gradually applies water pressure to a sample; the pressure at which water first appears on the non-contact side is recorded as the hydrostatic pressure.

(4) Why is this product important?

It ensures fabrics and protective materials meet waterproof and fluid resistance standards for outdoor, medical, and industrial applications.

(5) What industries is this product suitable for?

Textiles, outdoor equipment, medical and chemical protective clothing, filtration materials, paper and packaging, and industrial coatings.
