This instrument is used to measure the permeability of various types of Geotextiles and the water flow through the single layer geotextiles vertically under specified conditions.

GB/T15789、ISO11058、JTG E50、SL/T235、ASTM D471

1. Maximum head difference: 300 mm H_2O

2. Internal diameter of the holder: 50mm +1mm

3. Testable sample thickness: 0.1-10 mm

4. Flow range: 0-5L/min

5. Ground-type machine, equipped with water tank at the top of the instrument, meets the test requirements of samples with larger permeability.

6. The whole machine adopts imported 304 stainless steel; the worktable adopts imported special aluminium, sandblasting oxidation treatment, rust-proof and corrosion-proof, and the whole machine is relatively light.

7. Water penetrates upwards from the bottom of the sample without drop and bubbles will not form to ensure the accuracy of the test.

8. Four sets of flowmeters can accurately control the head pressure difference.

9. The maximum flow rate can be controlled to: 5L/min, which can accurately measure the permeability of single layer geotextiles.

10. Power supply: Ac220V + 10% 50Hz

11. Apparatus shape: 1200 x 620 x 1750 (mm)

12. Weight: 80Kg
