Sand gauge

A handy visual aid accor­ding to DIN EN ISO 14688–1 for deter­mi­ning par­tic­le size dis­tri­bu­ti­on on-site.

With its sub­di­vi­si­on into five essen­ti­al par­tic­le size cate­go­ries, from silt to sand and gravel, the sand gauge pro­vi­des a prac­ti­cal and visual means of com­pa­ri­son.
