【Scope of application】

YT020F vertical permeability tester for geosynthetics is a fully automatic operation and computer-controlled geotextile permeability coefficient testing equipment, suitable for geotextiles, textile fabrics, fiber nets, filter materials, sintered plates, porous thin metal plates, and plate-like porous Water permeability test of building materials and other related materials.

【Test Principle】

Comply with EN ISO 11058 standard, operate through the pressure difference method, test the pressure difference between the two ends of the vertical sample plane, without additional pressure, can detect the VIH50 rate index of the test material, meet the relevant standards and easy to operate. This system uses different rates of water flow through the sample to measure the pressure difference between the two sides of the sample for analysis.

【Standards compliant】

EN ISO 11058
