Geosynthetic Vertical Permeameter with Standar ISO 11058 ASTM D4491 EN ISO 10776 ASTM D4716

The geotextile vertical permeability testing instrument is a horizontal constant-head testing instrument designed and manufactured in accordance with the latest national standard GB/T15789-2005 and the newly released "Highway Engineering Geotextile Test Procedures" by the Ministry of Transport (JTG E50-2006). It is suitable for conducting vertical permeability tests on various geotextiles and composite woven fabrics with permeability properties under a constant water head. The national computer software copyright certificate number for the geotextile vertical permeability tester: Soft Copyright Registration No. 2452896.

Principle Overview: The flow velocity (in mm/s) of water flowing perpendicularly to the surface of the geotextile under a unit hydraulic gradient.

Instrument feature:
 1. This machine is equipped with a 7.8-inch high-definition touch color screen system and a Chinese menu operation interface.

 2. The test fixture is made of high-quality aluminum alloy, which is corrosion-resistant, easy to clean, and elegant.

 3. A transparent organic glass test chamber is used to prevent water splashes and dust from entering.

 4. The American DuPont powder and electrostatic painting process is adopted, which is cured at a high temperature of 200°C and does not fade.

 5. Sample clamping method: horizontal flow, sample placed in water, and sample is held by a force rod.

 6. The amount of water permeability and collection volume is measured using a graduated cylinder and displayed with high-definition scales.

 7. The entire machine has no exposed plastic hoses. A zero-pipe experimental chamber is used to effectively prevent bubble formation and ensure accurate data.

 8. The digital setting of water head difference, automatic positioning, and high precision.
