Geotextile Permeability Tester for Water Permeability Testing

Application:

The geotextile vertical permeability tester is a constant head tester designed and manufactured according to the requirements of the latest national standard GB/T15789-2016. It is suitable for testing the vertical permeability of various permeable geotextiles and composite geotextiles under a constant head. The machine adopts microcomputer program control, and the sensor collects and measures the water volume, and the permeability coefficient is automatically calculated.
