XR-100D series is used for detecting contaminants inside of the small packaged products. Metal and non-metal impurities include ferrous, non-ferrous, stainless steel, glass, ceramic, stone, bones, had rubber and hard plastic, even for products wrapped in aluminum foil or metallised film and etc.
The foreign object is detectable by its density. The greater density they have, the easier they can be found. That is why we normally use X-RAY inspection system to detect even the most tiny contaminants.
