Permeability
Permeability Cells
Permeability cells are constructed of high-quality materials throughout for long-lasting performance. The cell top and base are precision machined from 6061 T6 aluminum and then hard-coated and Teflon-impregnated for a durable finish. To facilitate sample setup, the chamber and cell top can be quickly and easily removed by loosening the three knobs that hold the upper assembly to the base. The clear acrylic chamber provides a working pressure of 150 psi (1,000 kPa) and is tested to 250 psi (1,700 kPa).
The cell has five, no-volume-change, valves aligned along the front of the cell for maximum convenience. Two valves handle top drainage, two valves handle bottom drainage, and one valve handles filling/emptying and providing confining pressure to the cell. Brass valves are standard with these cells, but stainless steel valves (stainless steel is typically used with hazardous materials) are an option,
Permeability Cells require a Top Cap and Base Pedestal Set for operation.

Permeability
(Permeameters for Permeability Testing, Compaction Permeameter)
Permeameters for Permeability Testing
supports the following standards: ASTM D2434, BS 1377 Part 5
Use to determine the coefficient of permeability by the constant head method for laminar flow of water through granular soils. Two manometer ports are grooved & screened on the inside. Distance between ports is always equal to diameter. 100 mesh screens used to prevent migration of material through valves and tubing during test. Acrylic chamber permits viewing sample. Spring incorporated into top cap to apply 5-10 lbs. force against top stone or screen to prevent soil density changes. End caps & clamping ring of anodized aluminum. Each chamber complete with: valves; porous stones or perforated screens, depending on the diameter of sample; tubing for connection to water source and manometer tubes. Permeameters without manometer outlets available
Compaction Permeameter
offers two sizes of Compaction Permeameters to measure constant or falling-head properties of compacted or remolded soils. The 4in and 6in Permeameters are constructed of plated steel for wear resistance and long life. Mold dimensions are 4x4.584in (101.6x116.4mm) and 6x7in (152.4x177.8mm), not including collars. These molds are similar to Proctor and CBR molds, except that the upper and lower plates have inlet/outlet connectors to allow the flow of water through the compacted sample. The overflow valve on the top plate is designed for air removal during the test. A porous stone filter is also provided. manometers are purchased separately and are required to measure top and bottom head pressures during permeability testing
