MarSurf M 400. The best of the "mobiles"
Surface evaluation using skidless tracing is not only needed in the measuring room but is required more and more in production as well.
This usually means higher demands on operator qualities, more time, more adjustment work.
In the line of "mobile surface metrology", MarSurf M 400 offers this required scope of performance and at the same time simple and fast operability.
