Inline verification stands for control in the production line. REA VERIFIER can support this verification with the measuring instruments, so that the results provided by Scanner inline are related to real measurement results. In addition, an automated, metrological sample inspection can be used to carry out a 100% metrological control for slow processes. With fast processes, it is possible to use automated unloading, measurement and loading to control a significantly higher and thus more significant sample quantity by means of measurement techniques than would be possible manually.
