The Werth TomoScope® is the first implementation of the above principle in the world. The mechanical components, and thus the device precision, are based on the ScopeCheck® concept. By selecting the appropriate X-ray components (voltage range of Xray tube, detector type), the device can be configured optimally for a variety of different materials. Low voltages, for example, are required for measuring plastic parts that have low density. High voltages are needed for measuring high-density metal parts.
