*25–50 mm measuring range *Resolution 0.01 mm for fine increments *Ratchet stop for consistent measuring force *Matte chrome thimble, DIN 863 compliant

Accurate incremental measurement for routine quality control

This outside micrometer delivers precise incremental readings with a resolution of 0.01 mm, supported by a spindle pitch of 0.5 mm that converts fine rotary movement into dependable linear travel. The visible counting dial simplifies repeatable subtraction of full turns and reduces reading errors when performing series measurements. Combined with the ratchet stop, the instrument enforces a consistent measuring force that minimises operator-induced variation, improving first-pass yield in production and reducing rework. These features make the device particularly suitable for component inspection where tight tolerances and rapid throughput are both required.

Robust construction that suits everyday workshop demands

Constructed with a matte chrome-plated thimble, the micrometer resists glare and offers a tactile finish that aids precise setting under workshop lighting. Conformity with DIN 863 ensures compatibility with established metrology routines and acceptance within standard quality processes. The instrument includes properly finished measuring faces and a stable spindle diameter of 6.5 mm, delivering the stiffness necessary to keep deflection low during contact measurement. The result is a tool that balances sensitivity with durability, designed to withstand the rigours of machine‑shop environments while maintaining measurement integrity.

Intuitive operation and service-friendly handling

The analogue display with counting mechanism provides a direct visual reference, enabling quick decisions on the shop floor without additional readout devices. The ratchet stop and the carefully calibrated spindle motion support consistent readings across repetitive checks, while the robust mechanical layout keeps maintenance straightforward. Routine checks and interval calibration are recommended to maintain traceability and performance; for tailored calibration intervals or verification procedures, Metav Werkzeuge can advise on practical schedules aligned with production cycles. This micrometer fits seamlessly into a quality-controlled workflow and supports measurable improvements in measurement reproducibility.
