Sand Size Card

USD $12.95

Our new and improved sand sizes card show the five primary sand particle sizes plus silt/clay according to the USDA and the Canadian System of Soil Classification (CSSC). The card is approximately 3″ (74mm) x 5″(125mm) and is made of durable, water proof plastic. The sand, silt and clay grains are affixed in recessed holes in the card. This protects the grains from being chipped or worn off the card while still allowing users to touch and feel the different size particles. The back of the card has a handy color annotated graphic depicting a typical soil profile and the different horizons.  A break-away style lanyard is included for convenience and safety.

Very handy for site evaluation and instruction in the field or classroom to help learners and experienced practitioners detect the difference between various sand textures and grades of sand.  Helpful also when explaining to homeowners or septic installers about gradation requirements and quality control issues with septic sand fill.

Sizes are: Silt & Clay (<0.05mm), Very fine sand (0.05 to 0.10 mm), Fine sand (0.10 to 0.25 mm), Medium sand (0.25 to 0.50 mm), Coarse sand (0.50 to 1.00 mm), Very coarse sand (1.00 to 2.00 mm).
