Abstract: A measuring device for detecting measuring signals during either a scanning across a surface to determine a surface profile or a penetration movement of an indenter into a surface of the specimen to determine hardness, and, scanning with sufficient force to determine the scratch resistance of the specimen is described. All of the measurements can be done on the same specimen without unmounting the specimen from a holder. A camera mounted to the same framework as the measuring device enables further documentation of the specimen being tested.
