Constant Head Permeability Set

UTS-1300B

The UTS-1300B Constant Head Permeability Set is used to examine the behaviour of relatively coarse-grained soil such as gravel and sands, in its natural conditions with respect to water flow.

The Constant Head Permeability Set is supplied complete with;

• Ø 80 mm or Ø 120 mm Permeability Cell with Pressure Points at 3 different levels and 2 pcs. Wire Gauze ( fit for the prefered cell dia. )
• Wooden Stand with 3 manometer tubes
• 3 m Hose

Falling Head Permeability Set

UTS-1320

The UTS-1320 Falling Head Permeability Set is used to examine the behaviour of soil with respect to water flow. It is particularly used with finegrained soils such as clay-like or silty soils.

The UTS-1320 Falling Head Permeability Set is supplied complete with;

• Ø 100 mm Falling Head Permeability Cell
• Wooden Stand with 4 manometer tubes
• Soaking Reservoir Tank

Permeameter Stand

UTS-1420

When used together with UTS-1401 Ø 4” or UTS-1402 Ø 6” Compaction Permeameters, the UTS-1420 Permeameter Stand is used to measure the water permeability of compacted soil samples such as clay, gravel, sand etc.

Pinhole Test Apparatus

UTS-1500

Water flowing through fine-grained soils with high sodium content makes them highly erodible.

The erodibility of clay soils can be measured using the UTS-1500 Pinhole Test Apparatus. This is done by flowing water through a small hole which has been drilled through the compacted specimen.

The apparatus comprises of a cylindrical metal container fitted one end with a water inlet and the other end with an outlet connection, a standpipe tube with scale and a stand to support the apparatus.
