Mahr was the first manufacturer of contour metrology offering the possibility of measurements with a twin stylus with simultaneous switching of the measuring force. This makes it possible not only to measure contours in one tracing direction but also to perform upside down measurements, thus enabling pairs of opposed profiles to be recorded and set off against each other, for diameter measurements, for example. Today we are proud to present to you a decisive development that builds upon these possibilities. In connection with the measuring stand MarSurf ST 750 D, the measuring stations UD 120 / LD 120 as well as XC 20 CNC can use the entire measuring length 620 mm of the vertical axis.
