Key Features
Water-resistant plastic card, 127 x 203 mm (5 x 8 in), on a lanyard.
Particle size classification by the Unified Soils Classification System.
Coarse and fine-grained soils in fifteen descriptive categories, from gravels and sands to silts and clays.
Sands graded from very loose to very dense; clays from very soft to hard.
Six colour chips, four patches of sized grains and four tables.
Worn on its lanyard, the card stays to hand while samples are described, letting the user match grain size against the sized patches, compare colour with the chips and check size against the edge scales. Separate guides grade sands by how loose or dense they are and clays by how soft or hard. Educational Lab Equipments can supply and export the Geotechnical Gauge to Bolivia, Honduras, Poland, Morocco and Cambodia.
