The vertical permeability tester of geotextile is a horizontal constant head tester designed and manufactured in accordance with the requirements of the national standard GB/T15789-2005 and the new release department of the Ministry of Communications of the "Highway Engineering Geosynthetics Test Regulation JTG E50-2006". It is suitable for Various geotextiles and composite fabrics with water permeability are tested for vertical permeability under constant water head.
YT020 Geotextile Water Permeability Tester (open constant head method) is used to test the vertical permeability coefficient and water permeability performance of geotextiles and composite materials in the unloaded state, constant head and in line with laminar flow conditions.
