Digital Micrometer M302.257 — 75–100 mm, 0.001 mm resolution

The Digital Micrometer M302.257 is a workshop-grade outside micrometer designed for accurate external measurements in mechanical engineering and quality assurance tasks.

• 0.001 mm digital resolution
• ON/OFF, SET, ABS/INC/UNIT display
• Ratchet stop for consistent force
• Measuring faces 6.5 mm

Increase measurement certainty with sub-micron readback

The instrument offers a 0.001 mm display step across the 75–100 mm measuring span, which converts fine movements into a clear digital readout and reduces readout uncertainty compared with coarse analogue scales. Compliance with DIN 863 underlines its suitability for routine inspection and component acceptance; the thin, well-defined measuring faces 6.5 mm give a small contact footprint that is advantageous when measuring narrow bosses, shafts or turned features. This level of resolution supports tighter process control and faster decision-making in production environments.

Consistent contact force and intuitive controls speed up workflows

A built-in ratchet stop ensures a reproducible measuring force, reducing variation caused by operator pressure and improving repeatability across a batch of parts. The digital display features ON/OFF, SET and ABS/INC/UNIT modes for switching between absolute and incremental readings, zeroing at any position, and selecting units quickly—features that translate into fewer setup steps and less post-processing of measurement data. The frame is painted for durable handling while the matt chrome-plated thimble improves visibility and resists wear, together supporting efficient, fatigue‑reduced operation on the workshop bench.

Robust construction designed for everyday use in the workshop

Hardened contact faces and a sturdy frame provide the longevity required for frequent use in machining and inspection stations. The instrument includes a practical setting gauge reference (setting gauge from 25–50 mm) for straightforward calibration checks and set‑up routines. As part of the Metav IndustryLine, this micrometer pairs industrial-grade mechanics with clear digital functionality, making it a reliable choice for tasks where reproducibility and traceable workmanship are priorities.

FAQ

What resolution does the micrometer provide?
The micrometer displays measurements with a resolution of 0.001 mm, allowing very fine discrimination within the 75–100 mm measuring range.

Is the device suitable for workshop inspection tasks?
Yes, the M302.257 is designed for workshop and quality-assurance use, complying with DIN 863 and providing repeatable readings for routine inspection and production control.

How does the ratchet stop affect measurement quality?
The ratchet stop ensures a consistent contact force at the measuring faces, which reduces operator-induced variation and improves repeatability across multiple measurements.

Which display functions are available for measurement modes?
The device includes ON/OFF and SET controls plus ABS/INC/UNIT functions, enabling zeroing at any point, switching between absolute and incremental modes, and changing measurement units.
