Floating holder It is especially suitable for the use with automatic measuring stations or with the measuring stand OSM5 and OSM 6, either for measuring series or for measuring in larger work pieces or whenever a high measuring accuracy is required. The floating holder allows the measuring instrument clamped-in to move radially by 0,5 mm. Furthermore, it provides a higher measuring certainty, because the probe is centred in the real measuring axis in the work piece.
