ASTM/AASHTO Permeameter, 6.0in Diameter

ASTM/AASHTO Permeameter, 6.0in Diameter

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

Each permeameter features two sidewall manometer ports covered with No. 100 (150µm) stainless steel mesh to prevent soil material from entering the manometer. A compression spring on the top cap applies 5–10lbs (2.3–4.5kg) of force to the top porous stone or perforated plate, ensuring consistent soil density during tests. Included anodized aluminum end caps have ports and valves for vacuum and water connections, and tubing is provided. Models in 6.0 and 9.0-inch sizes include porous plates for both the top and bottom of specimens, while smaller models come with porous stones.

A manometer is required for ASTM/AASHTO compliance and is sold separately. Options include the Free-Standing Manometer or Wall-Mounted Manometer.
