【Scope of application】
The automatic geosynthetic vertical permeability tester is a constant head tester designed and manufactured according to the latest national standard GB/T15789-2016 and the requirements of the Ministry of Water Resources "SL235-2012 Geosynthetics Test Regulations". It is suitable for various geotextiles with water permeability. And composite fabrics are tested for vertical permeability performance under constant water head. This machine adopts microcomputer program control, sensor acquisition and measurement, head difference digital setting, automatic positioning, automatic conversion of permeability coefficient, display, storage, statistics, editing, printing, etc.
