ASTM/AASHTO Constant Head Permeameters use the constant head method for laminar flow of water through granular soils to determine coefficient of permeability. Models HM-831 to HM-835 come in sizes ranging from 2.5-9.0in (63.5-228.6mm) diameter to accommodate granular soil permeability testing of a wide range of particle top sizes. The permeameter’s clear acrylic sample chamber allows for easy viewing during testing.

The Permeameters have two sidewall manometer ports covered with No. 100 (150µm) brass mesh to deter material into the manometer. A compression spring attached on the top cap to apply 5-10lbs force against the top porous stone or perforated plate to prevent soil density changes while running test. Also included are anodized aluminum end caps with valves and ports, and tubing for vacuum and water source 6.0 and 9.0in models include porous plates for use on top and bottom of the specimens, smaller sizes include porous stones.

A manometer, sold separately, is a required accessory for an ASTM/AASHTO compliant permeameter. Gilson offer the HMA-838 Free-Standing Manometer or the HMA-839 Wall-Mounted Manometer

Features:

  • Clear acrylic chamber for easy viewing
  • No. 100 mesh placed over manometer ports prevents loss of soil materials
