Mitutoyo – Outside Micrometer 150–175 mm, 0.01 mm Resolution (one side of the frame lightly ground)

This Mitutoyo OS Mic Outside Micrometer is designed for accurate external dimension measurement across the 150–175 mm range. The rigid frame provides stability, while the micrometer head delivers fine, repeatable readings with 0.01 mm resolution, making it suitable for tight‑tolerance machining and inspection tasks.

The hardened measuring faces ensure long‑term durability and consistent accuracy. This particular unit has one side of the frame lightly ground, likely for clearance or fixture use. The modification is cosmetic and does not affect measurement performance.
