The YT020CS type (vertical constant head method) is used to determine the vertical permeability coefficient and permeability of geotextiles and sheet composite geotextiles under specified conditions. This machine's geosynthetic material vertical permeability meter has a national computer software copyright certificate number: Ruanzhudeng Zi No. 2452896.

GB/T15789-2005 B method SL/T235-2012

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. Having the copyright certificate of geosynthetic material vertical permeameter software and a valid software qualification inspection and testing report issued by a national inspection and testing institution, with the "CMA" mark on the testing report.

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.
