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. Science Lab Supplies supplies the gauge from Ambala, India to institutes, contractors and distributors.
Specifications
The 127 x 203 mm (5 x 8 in) plastic card hangs on a lanyard and resists water on site. It carries six colour chips, four patches of sized grains and four classification tables, with separate 0–6 in and 0–110 mm scales along its edges for measuring particles and samples.

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 in geotechnical engineering.
- B.Sc. / M.Sc. geology: describing soils and loose sediments on field trips.
- 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
Field cards are usually ordered one per student or group, and a quotation can cover a single gauge or a class quantity, 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. Contact the team through the contact page, place items in the enquiry cart, or see the lab tender page for bulk tenders.
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 at trial pits, cuttings and boreholes.
Who supplies the Geotechnical Gauge?
It is supplied by Science Lab Supplies of Ambala, India, which quotes it to colleges, universities, training institutes, contractors and distributors.
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 soil classification.
Related Field Soil Identification Equipment
Field description is more reliable with matching references and follow-up tests, so these Soil Mechanics items pair with the gauge: two pocket charts for grain size and sand shape, a laboratory particle size set to confirm grading, and a core cutter for field density samples.
- Grain Size Chart — mounted grains on the Wentworth scale.
- Sand Gauge Chart — sand size and roundness panels.
- Particle Size Analysis Test Set — eight-jar hydrometer bath for the lab.
- Core Cutter — field density samples from the same site.
