Economy Manometer Tube Stand, Wall Mount

Used for permeability testing, this cconomical manometer tube setup is built for use with many permeameters. Two acrylic tubes with valves mounted on aluminum rail, with scale for monitoring flow volumes. Scale is 100cm long with cm and mm graduations. Each tube has its own valve to allow running two tests. Choose wall mount or free standing. Meets ASTM D2434. Shipping wt. 8 lbs. (3.7kg)

Economy Manometer Tube Stand, Free Standing

Constant Head Tank

Acrylic tank with regulating valve for flow control of water and a porous media on bottom to filter out air bubbles. Maintains constant water head via an overflow port. Includes: saddle valve for connection to either de-aired or tap water source; rails for wall mounting with easy height adjustment and tubing for hook-up to test chamber.

Constant Head Permeameter Cell

Constant Head Permeameter Cell. 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 & 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. Meets ASTM D2434; BS 1377 Part 5. Shipping wt. 7 to 12 lbs. (3.2 to 5.4kg)

Shelby Tube Permeameter

The Shelby Tube Permeameter allows you to perform permeability tests within a Shelby tube without removing the sample. Ideal for cohesionless materials and sands. Two sets of end caps fit over a Shelby tube liner up to 6" long. End caps each contain valve to control flow of permeants through the specimen, along with a porous stone to prevent material from flowing into and clogging the valve. End caps are anodized aluminum. Includes o-rings, connecting rods, clamping knobs and tubing. Shelby tube not included.

Compaction Permeameter, 4"

For determining permeability of clay, sand, and gravel soils. Uses Proctor plasticity compaction method. Two-piece cylindrical mold includes: upper plate with valve; water inlet/outlet; filter base plate; and filter stones. 4"W x 4"D x 12"H. Meets ASTM D5856. Shipping wt. 18 lbs. (8.16kg)

Compaction Permeameter, 6"

For determining permeability of clay, sand, and gravel soils. Uses Proctor plasticity compaction method. Two-piece cylindrical mold includes: upper plate with valve; water inlet/outlet; filter base plate; and filter stones. 6"W x 6"D x 12"H. Meets ASTM D5856. Shipping wt. 18 lbs. (8.16kg)

Constant/Falling Head Permeameter Set

Constant/Falling Head Permeameter Set for use with granular soils in determining the coefficient of permeability via the constant or falling-head method for laminar flow of water. Compact and portable unit includes manometer tube, scale and permeameter base attached to a platform. Funnel provides adjustable constant head reservoir. Spring incorporated into top capto apply 5-10 lbs. force against top stone or screen to prevent soil density changes. End caps & clamping ring of anodized aluminum. Set complete with: permeameter; manometer tube; two funnels; either porous stones or perforated screens depending on diameter, and tubing for connection to water source. Shipping wt. 13 lbs. (5.9kg)
