The PS25C inspection system is used to analyse transparent and opaque pellets. The testing material can be fed manually in a hopper or automatically by an online or a multi-hopper system. The pellets are transported on a vibrating channel pass the inspection zone. There the pellets are inspected with a high-resolution 3-CCD-chip colour camera for impurities, foreign bodies, or colour deviations. The purity scanner is great for measuring rapid reactions to occurrences.
