ASTM/AASHTO Permeameter, 3.0in Diameter

ASTM/AASHTO Permeameter, 3.0in Diameter

ASTM/AASHTO Constant Head Permeameters are designed to determine the coefficient of permeability in granular soils using the constant head method for laminar water flow. Available in sizes ranging from 2.5–9.0in (63.5–228.6mm) in diameter, these permeameters are ideal for testing a variety of granular soil particle sizes. The clear acrylic sample chamber offers easy observation during testing.

Each permeameter features two sidewall manometer ports covered with No.100 (150µm) stainless steel mesh to prevent material from entering the manometer. A compression spring on the top cap applies 5–10lbs (2.3–4.5kgs) of force to the top porous stone or perforated plate, maintaining soil density throughout testing. The units include tubing, anodized aluminum end caps with valves and ports for vacuum or water sources, and porous plates or stones based on the model size. Models with 6.0in and 9.0in diameters include porous plates for both the top and bottom, while smaller models include porous stones.

A separate manometer is required for ASTM/AASHTO compliance. Choose from our Free-Standing Manometer or Wall-Mounted Manometer options.
