The MITUTOYO Outside Micrometer 25–50mm (White Frame) is a precision measuring tool designed for accurate external dimension measurement of medium-sized components such as shafts, rods, and machined parts.

With a measurement range of 25–50mm, this micrometer is typically used as the second essential size after the 0–25mm model in any workshop measurement set. It features a 0.01mm graduation (or finer depending on model), ensuring reliable and repeatable results for industrial and engineering applications.

The micrometer is equipped with a ratchet stop mechanism, which applies constant measuring force and improves accuracy by reducing user variation. High-quality models include carbide-tipped measuring faces, ensuring long-term wear resistance and maintaining precision over time.

Its heat-insulated, enamel-coated (white) frame minimizes the effect of temperature changes from hand contact, helping maintain measurement accuracy in real working conditions.
