Geotechnical Gauge
Product Code : LSK-SM-10667
Geotechnical Gauge (SKU LSK-SM-10667) is a water-resistant field reference card that helps students and site technicians describe and classify soils by eye and touch. Colour chips, sized grain patches and printed tables cover clay consistency, particle size, soil type and sand density. It suits geotechnical field classes in civil engineering, geology and TVET survey courses. Institutes, contractors and distributors buy the gauge from Science Lab Supplies, which sends it out from Ambala, India.
Specifications
The field card's details are split into one fact per row in the table. In short, it is a water-resistant 127 x 203 mm plastic card on a lanyard with six colour chips, four sized-grain patches and four classification tables, plus separate 0–6 in and 0–110 mm scales along its edges.

Applications and Experiments for the Geotechnical Gauge
In the field the gauge is used to log soils consistently: rating clays from very soft to hard, sorting soils by particle size under the Unified Soils Classification System, placing coarse and fine-grained soils in fifteen descriptive categories, and judging sand from very loose to very dense.
- B.Tech / B.E. civil engineering: field identification and borehole logging exercises, with density samples taken by Core Cutter from the same trial pit.
- B.Sc. / M.Sc. geology: describing soils and loose sediments on field trips, with grains inspected through a Double Lens Folding Pocket Magnifier.
- TVET survey, construction and site investigation modules: recording soil descriptions on site.
Standard Scope of Supply
Each Geotechnical Gauge is supplied as one printed plastic card on its lanyard, as described above. For class field kits, several gauges can be quoted together with the grain size and sand gauge charts from the same Soil Mechanics range.
Packing, MOQ and Lead Time
A quotation can cover a single gauge or one for every student or group in a class, stating packing, delivery time and price for that number. Adding related charts or field density kits keeps vocational training equipment for site courses on one order.
Science Lab Supplies can ship to buyers in Peru, Egypt, Iraq, Nigeria, Kenya and Ghana as a registered exporter holding an Importer-Exporter Code. Class sizes can be passed on through the contact page, gauges added to the enquiry cart with other field kit, and bulk tenders lodged through the lab tender page.
Frequently Asked Questions
What can be classified with the Geotechnical Gauge?
Clay consistency from very soft to hard, soil type by particle size under the Unified Soils Classification System, fifteen descriptive categories from gravels to clays, and sand density from very loose to very dense.
Can it be used in wet conditions?
Yes. The card is water-resistant plastic and hangs on a lanyard, so it can be carried and handled in the field at trial pits, cuttings and boreholes.
Who supplies the Geotechnical Gauge?
Science Lab Supplies provides the gauge from Ambala, India. Universities, colleges, training institutes, contractors and distributors can ask for one card or a class quantity, and the quotation confirms the number of cards offered.
Does the gauge replace laboratory tests?
No. It gives a consistent field description, while sieve, hydrometer and Atterberg limit tests in the laboratory remain the basis for formal classification of the soils you collect.
