The 3-position Standard and 6-position Add-on panels are an air operated pressure control panels for permeability and triaxial testing. It consists of a control section and three or six pressure positions.
The Flexible-Wall Permeameters are designed for measurement of hydraulic conductivity of cylindrical soil specimens. Permeameters are available for maximum diameters of 3″, 4″, 6″, 8″, and 12″ specimens.
The Bladder Accumulators consists of a flexible bladder clamped between two stainless steel chambers. The flexible bladder serves as a fluid separator and prevents the permeant from entering the control panel. Volume capacity 200 mL and 1500 mL.
Testing with the Permometer conforms to ASTM D5084 and classifies as a falling head – increasing tail test, Method C. ASTM D5084 termination criteria are typically achieved within 1 to 24 hrs after specimen saturation.
The Constant Head Permeameters (CHP) are designed for measuring hydraulic conductivity of coarse grain soils, i.e., silts, sands, and gravels. Standard sizes accommodate four-inch and six-inch specimen molds. Various sizes available on request.
The Double-Ring Permeameter (DRP) is an improved version of the compaction permeameter, the main difference being the DRP’s ability to detect sidewall leakage. Standard version – 4″ other diameters available upon request
