Hydrostatic head Tester

　　Introduction

　　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.

　　Feature

　　The pneumatic chuck with pressure regulating function, can provide superior clamping force, even under high pressure test condition, there will not occur leakage failure lead to test failure; at the same time ,it can meet the long-term test of the seal; chuck control has two ways to choose, mechanical button control and touch screen control.

　　LED observation light with high brightness, good visual in all directions, to ensure that the observation conditions is facilitate to observe and confirm the three drops of water test end point.

　　7-inch color screen, capacitive touch screen, multi-point touch operating system, easy to control, multi-language display, switch between Chinese – English language. 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.
