Outside micrometer 50–75 mm (M304.250) – large thimble with friction ratchet, Metav IndustryLine

A precision outside micrometer 50–75 mm designed for external diameter measurements in workshop and inspection environments, conforming to DIN 863.

• Large thimble for fine reading
• Friction ratchet for reproducible force
• Matt‑chrome plated thimble
• Supplied in protective case

Consistent precision for production and inspection

The instrument delivers a resolution of 0.01 mm, supported by a spindle pitch of 1 mm, which together provide straightforward, repeatable graduations on the thimble. The mechanical design, featuring a large thimble and clear scale divisions, reduces reading errors and speeds up routine checks. The inclusion of a friction ratchet regulates the applied measuring force so that every reading is comparable and independent of operator pressure—an important factor in reducing process variance and rework.

Robust construction that promotes long service life

Built to workshop standards, the micrometer uses a matt‑chrome plated drum that resists glare and supports precise reading under workshop lighting. The measuring faces are hardened, providing wear resistance and stable contact geometry for long‑term accuracy. With a weight of 0.8 kg the instrument feels substantial in hand, aiding stable placement during measurement; its classification within the standard 50–75 mm range makes it suitable for a broad set of machining and inspection tasks where reach and rigidity must be balanced.

Practical operation tailored to industrial workflows

Marked to DIN 863, the micrometer integrates familiar mechanical conventions so it fits seamlessly into existing quality routines and documentation. The friction ratchet ensures a constant measuring force, while the thimble scale and spindle pitch make incremental adjustments intuitive. Delivered in a protective case, the instrument is ready for transport and safe storage between shifts. Together these attributes support efficient measurement cycles and help maintain traceable, repeatable results on the shop floor.
