• Meets ASTM D-2434 Test Specifications.
• Supplied complete with tubing and hardware.
• Accessory Manometer Panel and Constant Head Tank Assemblies.
The Sand/Gravel Permeameter is used specifically for testing the permeability of granular soils. Manufactured in accordance with ASTM D-2434 test specifications, the permeameter is designed to provide accurate results when performing the constant head test method for the laminar flow of water through granular materials.
Each permeameter comes equipped with valves, porous stones and tubing for connection to a water source, vacuum, and manometer tubes. To prevent soil density changes during the test, a spring is incorporated in the top cap to apply 5 to 10 lbf. (2.2 to 4.5 kg) against the top porous stone.
Two manometer ports are grooved and screened on the inside of the chamber. The screens prevent material from migrating through the valves and tubing during testing. The acrylic chamber permits viewing of the sample during testing. The end caps and clamping ring are constructed of anodized aluminum for rust resistance and long service life.
The system consists of an acrylic tank with regulating valve for flow control of water. A porous media is used at the bottom of the tank to filter out air bubbles.The unit maintains a constant water head by utilizing an overflow port. It also allows for connection to a tap water or de-aired water source. A wall mounting support, consisting of two rails with adjustable height brackets and tubing for connection between the tank and permeameter is included.The system consists of an acrylic tank with regulating valve for flow control of water.

The Manometer Panel features two acrylic tubes and valving mounted on an aluminum rail with a 100 cm long dualgraduated scale. Each tube has its own valve, making it possible to run two independent permeability tests. ...
