20140828_SpecCheck_10_01Spec-Check® consists of an integrated system of screens of various sizes contained inside a transparent container.  A sand sample is applied along with a small amount of water; after the device is agitated for a few minutes, the sample will be sorted based on the particle sizes of its content. Spec-Check® enables the user to evaluate the sand quickly, onsite and before construction proceeds in order to determine whether the supplied material meets specs.
