Mitutoyo 323-251-30 | Digital Disc Micrometer | 25–50 mm, 20 mm Discs

The Mitutoyo 323-251-30 is a Series 323 Digimatic disk micrometer with 20 mm measuring disks and a 25-50 mm measuring range. It is designed for measuring gear root tangent lengths, thin flanges, ribs, narrow recesses, and soft materials such as rubber, felt, cardboard, and fabric. The Digimatic data output allows measurement readings to be transferred directly to SPC and data collection systems, while the ratchet stop provides consistent measuring force for repeatable results.

The disk-shaped measuring faces allow the micrometer to reach narrow areas that are difficult to measure with standard micrometers. The 20 mm measuring disks are particularly useful for gear measurement and thin-section applications. The ratchet stop helps maintain consistent measuring force, while the Digimatic output supports efficient digital data collection. For accurate results, allow the micrometer and workpiece to reach the same temperature before measurement and avoid prolonged contact with the frame.
