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 furnishes the system from Ambala, India to institutes, tender contractors and distributors on request.
Specifications
The permeameter's three units are broken down row by row in the table. In short, a 3 kg, 75 mm (b) type cell with a movable stem feeds three manometer tubes on a 320 x 1450 x 500 mm bench standpipe, while a transparent constant level tank on a wall support keeps the head steady.

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, collecting seepage in a Measuring Cylinder Glass and timing it with School Digital Stopwatches.
- 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 part of the system and can be quoted separately.
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. Installation questions about the wall tank or bench standpipe can go through the contact page, the system can be added to the enquiry cart, and tender lists can be lodged on the lab tender page.
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, located in Ambala, India, supplies the complete system. Engineering colleges, materials labs, TVET centres, contractors and distributors get a quotation that lists the cell, standpipe and constant level tank separately.
