Design: With a clock positioned at a 20° angle. High-precision feeler gauge measuring instruments with gemstone-supported measuring mechanism in a compact, robust design. The housing and dovetail holding prisms are made from a single piece, ensuring particularly high rigidity during clamping. Corrosion protection through matte chrome plating of the housing. Mitutoyo – gemstone-supported measuring mechanism with hard metal measuring ball. Insensitive to magnetic fields. Spare part: Replacement probe with hard metal or ruby ball can be easily ordered. Delivery includes: Including clamping pin with a diameter of 8 mm. Usage: As an accurate comparison measuring device for checking the deviation from nominal dimensions for run-out tests, internal measurements, checking parallelism and flatness, as well as for aligning workpieces.
