Triaxial / Permeability Control Panels combine precise control, logical layout and quality components for use in triaxial and flex-wall permeability testing of soils. These panels offer sturdy cabinet construction with controls for air pressures located on the upper half of the panel and controls for water pressures on the lower half. Precision regulators set and control pressures, and zero-displacement ball valves are used for positive shutoff. Two 50cc burettes with 0.1cc graduations for flow measurement, and two 4cc pipettes with 0.008cc graduations are included. These are located inside two storage chambers which have additional capacity of 400cc each.

Cell water interface utilizes a 20cc burette. The panel and cell can be conveniently filled and drained from the front panel. A bias control feature allows the user to set the effective cell pressure and increase both cell and sample back pressure using only one regulator. This minimizes air consumption during saturation and causes no change in effective stress. Easy-access air, water, vacuum and drain connectors are located on the rear of the panel. All connections and tubing for the cell are conveniently located on the front of the panel.

Master Panel w/ Pressure Readout is ready for use with a single Triaxial or Flex-Wall Permeability Test Cell. The Master Panel includes a factory-installed digital readout for setting Test Cell and sample pressures. To control additional Triaxial or Flex-Wall Permeability Test Cells, an Add-On Panel can be connected to the Master Panel. Up to two (2) Add-On Panels can be connected to a single Master Panel.
