The geotextile vertical permeability tester is a constant head tester designed and manufactured according to the requirements of the latest national standard GB/T15789-2005 and the water conservancy SL235 standard. It is suitable for testing the vertical permeability of various geotextiles and composite geotextiles with permeability under a constant head. The machine adopts microcomputer programming, sensor acquisition and measurement, head difference digital setting, automatic positioning, permeability coefficient automatic conversion, display, storage, statistics, editing, printing, etc. The national computer software copyright certificate number of the geosynthetic material vertical permeability tester of this machine is Soft Copyright Registration No. 2452896.

GB/T15789-2005 、SL/T235-2012

Flow velocity of water flowing perpendicular to the plane of geotextile under unit hydraulic gradient (mm/s)

1. This machine adopts a 7.8-inch high-definition touch color screen system and a Chinese menu operation interface.

2. The testing fixture is made of high-quality aluminum alloy material, which is corrosion-resistant, easy to clean, and aesthetically pleasing.

3. Data collection: Bidirectional control between the host and PC (optional), automatic calculation of permeability coefficient, resulting in surface treatment of the printer body.

4. Adopting a transparent organic glass testing chamber to prevent water splashing and dust from entering.

5. Using DuPont powder from the United States and electrostatic spray painting process, it solidifies at a high temperature of 200 ℃ without fading.

6. Sample clamping method: water sampling, force rod clamping sampling, or pneumatic fixture sampling (optional)

7. The permeable water collection volume is measured using advanced laser methods with a high degree of automation.

8. Numerical setting of water head difference, automatic positioning, automatic conversion of permeability coefficient, statistics, editing, and printing.
