Digital micrometer M302.075 (Metav IndustryLine) – 25–50 mm, 0.001 mm resolution

The Digital micrometer M302.075 is a workshop-grade external measuring instrument designed for precise dimensional control in machining and inspection tasks, covering a practical measurement range for components and toolmaking.

• High resolution 0.001 mm display
• Friction ratchet for consistent measuring force
• RB 6 data output for traceable logging
• Conforms to DIN 863

Precision where consistent readings matter

The micrometer is built around a high-resolution measurement system with 0.001 mm graduation, delivering fine incremental readings that support tight tolerance control. With a measurement range 25–50 mm, the instrument targets the common span used in component manufacturing and toolmaking, offering an optimum balance between reach and stiffness. The inclusion of a friction ratchet ensures a reproducible contact force, reducing operator-induced variance and improving repeatability for serial measurements. Conformity with DIN 863 underlines its suitability for workshop and inspection use where recognised standards are required.

Efficient data handling for quality workflows

Equipped with data output RB 6, the micrometer facilitates direct transfer of measured values into inspection software or SPC systems, speeding up documentation and reducing transcription errors. The digital display provides clear numeric feedback and includes ON/OFF, SET, DATA and mm/inch/0 functions for straightforward operation and unit switching. These features support rational quality processes by shortening the time from measurement to analysis and enabling consistent record keeping for audit and traceability.

Designed for practical workshop use

Engineered for everyday handling, the measuring faces of 6.5 mm diameter give a compact contact area that suits small and medium-sized parts while offering robust surface contact. The instrument's overall construction yields a manageable mass of 0.7 kg, helping stable placement during measurement without unnecessary bulk. The friction ratchet also contributes to ergonomic handling by preventing over-tightening and ensuring a steady feel during repeated checks—benefits that keep inspection routines efficient and reduce operator fatigue.

Where this instrument adds value

Well matched to precision workshops, toolrooms and small-series production, the micrometer is appropriate for dimensional checks on turned parts, gauges and fittings as well as incoming goods inspection. Its combination of fine resolution, consistent measuring force and digital data export supports lean inspection practices and strengthens process control. For organisations aiming to tighten tolerances and improve measurement documentation, this solution supplies the essential metrological functions in a compact format.
