[Principle Overview]
Flow velocity of water flowing perpendicular to the plane of geotextile under unit hydraulic gradient (mm/s)
[Instrument Characteristics]
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 fully transparent organic glass testing chamber, the testing process is intuitive and clear.
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: horizontal water flow, sample loading in water, sample clamping with force rod.
7. The permeable water collection volume is measured using a graduated cylinder and displayed on high-definition scales.
8. The whole machine has no exposed plastic hoses and adopts a zero pipe experimental chamber to effectively prevent the generation of bubbles and ensure accurate data.
