Knowledge of hydraulic conductivity (water flow) characteristics of soils is essential in today’s environmentally regulated world of waste facilities, landfills and holding ponds.
Permeability studies normally require multiple samples to be tested under different moisture and unit weight conditions and can be very time consuming. Impact offers a variety of Control Panels, Test Chambers and permeability accessories to accommodate various requirements.
- The Permeability Master Control Panel combines precise control, logical layout, and quality components for accuracy and ease of operation.
- An LCD display shows all necessary confining and cell pressures.
- Precision regulators and valves allow accurate setting and control of cell and burette pressures during saturation, consolidation and testing phases of the procedure.
- The upper controls regulate air pressure to the permeability chamber, whilst the lower controls regulate the water supply.
- All cell and burette pressures are individually selectable and easily monitored on a single digital readout.
- The user sets the effective cell pressure and controls both cell and sample back pressure by adjusting one regulator. This is particularly useful during saturation and causes no change in effective stress.
- The test cell and panel reservoirs can be conveniently filled and drained from the front panel.
- All connections and tubing for the cell are located on the front panel.
- Water, air, and drain connectors are located at the rear of the panel.
The panel also includes two 50cc burettes graduated to 0.1cc and two 4ccpipettes graduated to 0.008cc, for accurate measurements of flow during the permeability test phase. Each is encased in a large 400cc capacity storage reservoir. The panel frame is constructed of sturdy aluminium and coated with epoxy paint for increased durability in harsh laboratory environments. Whitey™ high-quality ball valves are used to insure positive shut off of the valves.
The Panel is 533mm wide x 159mm deep x 946mm high.
An air compressor is required to generate confining pressures. This must be purchased separately.
