Hydrostatic Head Tester

The hydrostatic head tester is designed to test the pressure that the material does not come into contact with the exuded water droplets side when the water pressure is continuously raised in a standard atmospheric environment, which is the hydrostatic pressure value of the material. It can quickly and accurately test out the encountered resistance when water penetrates through the material, to assess the material waterproof and moisture permeability.

Application

The hydrostatic head tester can be used for waterproof moisture permeability testing of high density fabrics, laminated fabrics, coated fabrics and the so on, such as canvas, felt cloth, tarpaulin, airtight fabric, outdoor sportswear material, umbrella test, waterproof fabric testing, etc .; it can also be used for testing the body fluid permeability and blood permeability of medical protective clothing, the chemical liquid permeability of chemical protective clothing; breathable waterproof non-woven / non-woven fabric, permeability test of filter fabric; it can also be applied to water resistance test for paper and paperboard.

System with built-in standard, select the corresponding standard number to start the corresponding standard requirements of the dynamic and static test; also includes dynamic and static custom test mode.

FAQ

(1) What does the hydrostatic head test measure?

The hydrostatic head test measures the pressure level a material can withstand before water penetrates through it. The result reflects the waterproof performance of fabrics, coatings, and protective materials and is widely used in textile, outdoor equipment, and protective clothing quality evaluation.

(2) Which materials can be tested with this instrument?

The tester is suitable for fabrics, coated textiles, laminated materials, tarpaulins, outdoor clothing fabrics, medical protective materials, nonwoven fabrics, filter materials, and paper products requiring water resistance evaluation.

(3) How does the pneumatic clamping system improve testing accuracy?

The pneumatic clamp provides stable and uniform pressure on the sample surface, reducing leakage caused by uneven manual clamping. This helps maintain reliable test conditions, especially during high-pressure testing according to standards such as ISO 811 and AATCC 127.

(4) Can the tester perform different standard test methods?

Yes, the system includes built-in standard testing programs and supports dynamic and static test modes. Users can select corresponding methods according to requirements such as AATCC 127, GB/T 4744, ISO 811, and JIS L1092.

(5) How should a laboratory select a suitable hydrostatic head tester?

Selection should consider testing pressure range, sample size, applicable standards, clamping method, and data management requirements. QINSUN instruments are calibrated and tested before shipment to ensure measurement accuracy.
