Permeability Test System
Product Code : LSK-SM-10673
Permeability Test System (SKU LSK-SM-10673) is a constant-head permeameter setup for measuring the permeability of cohesionless soils and a wide range of construction materials. It combines a 75 mm permeability cell, a three-tube manometer standpipe and a wall-mounted constant level tank. Geotechnical and materials labs in engineering colleges and TVET centres use it. Science Lab Supplies supplies the system from Ambala, India to institutes, tender contractors and distributors.
Specifications
The 3 kg, 75 mm cell has a movable stem that stabilises the top surface of the sample, a metal base with inlet and drainage ducts, and a central body with three outlets feeding three manometer tubes. The bench-mounted standpipe measures 320 x 1450 x 500 mm.

Applications and Experiments for the Permeability Test System
Water from the constant level tank flows through the sample at a steady head while the three manometers show the head loss along its length and seepage water is collected and timed. From flow, gradient and area, students calculate the coefficient of permeability of granular soils and materials.
- B.Tech / B.E. civil engineering: constant-head permeability test on sands and gravels.
- M.Tech geotechnical and highway materials labs: drainage properties of filter and base materials.
- Diploma civil and TVET construction materials modules: comparing the permeability of different sands and aggregates.
Standard Scope of Supply
The system comprises the 75 mm (b) type permeability cell, the standpipe with three manometer tubes on its bench pedestal, and the constant level tank with its wall-mounting support. Connecting tubing, a measuring cylinder and a stopwatch are not in the listed contents.
Packing, MOQ and Lead Time
One complete system or several for a class can be quoted, and the quotation states the packing, delivery time and price for that quantity. A falling-head soil permeability apparatus can be added for fine-grained soils, giving a TVET workshop equipment list that covers both methods.
Science Lab Supplies, registered as an exporter with an Importer-Exporter Code, can ship to buyers in Ethiopia, Tanzania, Uganda, the UAE, Saudi Arabia and Oman. Write to us through the contact page, save items in the enquiry cart, or follow the lab tender page for tender supplies.
Frequently Asked Questions
Is this system for constant-head or falling-head tests?
The (b) type cell is designed for constant-head tests on cohesionless soils. For falling-head tests on finer soils, the Soil Permeability Apparatus with its three standpipes is the matching item.
What do the three manometer tubes show?
They connect to three outlets on the cell body and show the water head at points along the sample, so the hydraulic gradient can be read directly.
How is the system installed?
The standpipe mounts on a bench on its metal pedestal, and the constant level tank comes with a support for wall mounting so it can provide the steady head.
Who supplies the Permeability Test System?
Science Lab Supplies supplies the system from Ambala, India to engineering colleges, materials labs, TVET centres, contractors and distributors.
