Wenzhou Jigao Testing Instrument Co., Ltd.   

One, the instrument is based on the "osmotic properties of composite geomembrane determination of GB/T17642 - 1998" and "test methods of Geosynthetics for highway engineering JTGE50-2006" design and development. For the determination of the seepage water pressure difference under the provisions of a certain period of time the specimen (i.e. the seepage velocity) and thickness of specimen can be obtained by calculation, the permeability coefficient. This system adopts automatic cycle water pump control mode, use the load pressure digital display instrument, can unite the microcomputer. Two, the structure principle of the instrument is composed of a machine frame, a water tank and a submersible pump (circulating water), pressure regulator (differential pressure applying device),
