Werth profile- and measurement projectors allow rapid comparison of drawings in the workshop environment and secondly, with the aid of the Werth %u201DTastauge%u201D first proposed by Dr. Werth in 1977, they can be used for highly-accurate and fully-automatic measurements.

Minimal distortion in the image field and calibration corresponding to VDI/VDE 2617 and/or ISO 10360 guarantee corresponding trace-ability of measurement values to the linear
standard of the Physical Technical
Federal Institute (PTB).
