OVERVIEW:
\nThe Grain Size Card is an essential field geology reference tool for the visual classification of sediments by both size and shape. Brunton knows geology and we are proud to offer and add our rendition of the classic grain size card to our growing list of geology accessories. This lightweight and durable Grain Size Card is perfect for geology professionals and students working in the field who pay particular attention to sediment characteristics. Printed on a clear and rigid plastic, this card can help determine grain size classification with grain references from very coarse to very fine and their associated metric and phi equivalents. A grain shape scale and edge millimeter ruler complete the card. Our grain size card is an essential accessory and tool for field sediment classification work.<\/p>\n

FEATURES
\n\u25c6 Waterproof, durable, lightweight card can handle exposure to any type of weather
\n\u25c6 Transparent card stock with both a negative and positive sides for easier reading and comparing grain size in the field
\n\u25c6 Card data:
\n> 10 grain size classifications including phi scale
\n> Grain shape reference
\n> Millimeter ruler<\/p>\n

SPECS
\n\u25c6 dims: 2.5\u201d x 3.675\u201d x 0.06\u201d | 6.35 x 9.33 x 0.2cm
