Presby Spec-Check - Materials Analyses Device - Manual

Spec-Check (patent pending), developed by and available exclusively from Presby Environmental, is a portable, hand-operated device used for sorting/grading a sample of aggregate, sand or other particulate material in order to determine whether a sample meets a specification for an intended use. Unlike a lab analysis, the Spec-Check does not need the sample to be oven dried to remove all its moisture content. The device is small and easy to operate, making onsite examination of materials a quick and cost-effective alternative to expensive and time-consuming sieve analyses by a laboratory. A Spec-Check analysis gives a “go / no-go” indication in order to assist the user in determining whether the material can be used for a particular purpose, if a full sieve analysis is required, or if an alternative supply of aggregate is needed. SpecCheck can be customized to incorporate screen sizes that are representative of the specifications used for a variety of applications in the masonry and construction fields.
