The American standard vertical permeameter is used to measure the permeability coefficient (permeability) of industrial fabrics in an uncompressed state based on the permeability rate under standard test conditions. This machine adopts microcomputer programming, sensor acquisition and measurement, digital setting of water head difference, automatic positioning, automatic conversion of permeability coefficient, display, storage, statistics, editing, printing, etc. The national computer software copyright certificate number of this machine's geosynthetic material vertical permeameter is Soft Publication No. 2452896.

ASTMD 4491 Standard Test Method for Determining the Permeability of Geotextiles by Permeability Rate

The volumetric flow rate of water per unit cross-sectional area and unit head vertically passing through geotextile under laminar flow conditions.

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.
