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.

Performance Test (Constant Water Head Method)
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.
