M312.233.PN — Digital three-point internal micrometer, 12–16 mm, IP65, carbide faces (Metav IndustryLine)

The M312.233.PN is a compact digital three-point internal micrometer designed for fast, accurate measurement of small bores and blind holes in workshop and production environments.

Digital readout with mm/inch and HOLD function IP65 protection for dust and coolant resistance Carbide measuring faces for wear-resistant contact

Repeatable small-bore measurement for production control

The three-point contact geometry ensures stable centring inside bores, producing highly repeatable results in tight diameters. With a measurement range of 12–16 mm classified in the micro category, this instrument is ideal where compactness and stiffness matter for precision work on small components. The combination of a 0.001 mm resolution and a specified accuracy of 0.005 mm provides a clear, quantitative basis for in-process inspection and sorting, reducing rework and increasing throughput.

Robust construction that survives the shop floor

Built with carbide measuring faces, the gauge resists wear from repeated contact and abrasive contaminants, extending service intervals and preserving calibration. The IP65 rating protects the electronics from dust and washdown fluids, which means stable performance even in harsher production conditions. The unit’s overall design balances durability with a compact footprint, making it suitable for bench use or on jigs where access is restricted.

Digital functionality and traceability for modern workflows

The instrument features a clear digital display with ON/PRESET, mm/inch conversion and a HOLD function for reading in awkward positions. A data interface (RB 6) is provided for straightforward transfer to inspection systems or SPC software, enabling faster documentation and trend analysis. Conformity with DIN 863 ensures the measuring concept follows established standards, supporting quality records and audits.

Ready-to-use delivery and practical accessories

The micrometer is supplied with a setting ring for quick zeroing and an extension (150 x Ø11.8) to reach recessed or difficult-to-access bores, so measurement routines can begin immediately. Delivery in a protective case ensures safe transport and storage between jobs. The construction and included accessories make this a turnkey solution for workshops requiring reliable internal diameter checks, especially for blind-hole measurements where contact stability is critical.
