The Clean-N-Weigh accessory offers the fastest and most efficient method of processing large, coarse aggregate samples for particle size tests. After separation in a Screen Shaker, screen trays are dumped and cleaned directly into the Clean-N-Weigh. The material is then collected in the handling pan below, which rests on a suitable platform scale. The accumulated fraction weights are read directly from the tared scale and recorded. Handling pan and cleaning brush included. Scale sold separately.
