Digital outside micrometer M302.027.C — 400–500 mm, 1 µm resolution (Metav IndustryLine)

The Digital outside micrometer M302.027.C is a large‑range external measuring instrument designed for accurate dimension control of jigs, fixtures and sizeable machined components.

• 1 µm digital resolution display
• Carbide measuring faces for wear resistance
• Ratcheted spindle for constant measuring force
• RB 4.1 data output for digital logging

Reliability for larger parts and repeatable precision

This instrument is tailored for mid‑range inspection tasks where reach and stiffness must be balanced. With a measuring range of 400–500 mm it falls into the medium category of workshop micrometers, offering the reach required for larger assemblies while remaining manageable for single‑operator checks. The 0.001 mm display resolution provides submicron readability and, together with a stated accuracy of 0.013 mm, delivers the reproducible results needed for routine quality control in toolmaking and mould construction. The carbide measuring faces resist wear during repeated contact with hard materials and extend the service life of the tool.

Consistent measuring force and ergonomic handling

A ratcheted spindle and a spindle pitch of 0.5 mm ensure consistent contact pressure and minimise operator‑induced variance during measurement. The matt‑chromed measuring drum improves legibility while resisting glare in brightly lit inspection areas. The instrument’s digital unit features ON/OFF/SET, ABS/INC and UNIT buttons for straightforward operation and fast changeover between metric and imperial readouts. Physical design choices focus on steady support and an intuitive measuring routine, which speeds throughput and reduces rework in production environments.

Digital integration and workshop readiness

Data export via RB 4.1 enables straightforward logging into inspection software or SPC systems, supporting traceable measurement records and batch documentation. The device is supplied complete with a protective transport case to safeguard accuracy during handling and transit, and it is built to the manufacturer’s Werksnorm for consistent production standards. Applications include incoming inspection, in‑process verification and final part checks across steel, aluminium and other common workshop materials — the micrometer bridges hands‑on measurement with digital workflows for efficient quality assurance.
