Canstrat's Sand Grain Size Comparator

The Canstrat Sand Grain Size Comparator is a valuable tool for geologists and field technicians to quickly and accurately identify the size, shape, sorting, roundness, and sphericity of sand grains in the field. This pocket-sized comparator offers a visual reference for comparing sand samples against standardized grain sizes and shapes.

Key Features:

• Standardized Grain Sizes: The comparator features visual representations of various sand grain sizes, including silt, very fine sand, fine sand, medium sand, coarse sand, and very coarse sand.  
• Shape Examples: Includes illustrations of different grain shapes, such as angular, subangular, subrounded, and rounded.
• Sorting Examples: Provides visual examples of well-sorted and poorly-sorted grain samples.
• Sphericity and Roundness Chart: Includes a chart for measuring the sphericity and roundness of grains.  
• Pocket-Sized Design: Convenient for field use and easy to carry.
