Sand Grain Size Chart

Model: HM-510
Price: $16.00

Sand Grain Size Chart is a pocket-size visual soil classification system widely used by field technicians and geologists. The chart is used as a reference tool for describing soil samples and initial site evaluations. This grain size comparator card identifies sand granules in six sand grain sizes and shapes ranging from very coarse sand to silt sand.

It has die-cut cavities filled with precision-sieved sand sediment grain particles permanently mounted to the chart. Sand particle sizes are classified according to the Wentworth Scale. Particles are also designated by shape as angular, sub-angular, sub-rounded and rounded. Granules, pebbles, cobbles, and boulders are indicated by the range of size in millimeters.

It also designates scales of sphericity and roundness. The card further indicates well-sorted to poorly-sorted granular materials by diameter and is classified as coarse, medium, and fine.
