[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. 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.
