Digital three-point internal micrometer M312.212 — 10–12 mm, digital display (mm/inch), RB6 output

The Digital three-point internal micrometer M312.212 is a compact, workshop-ready instrument designed for reliable internal bore measurement, optimised for blind-hole inspection and fine mechanical applications.

• Digital readout with mm/inch and HOLD function
• High repeatability with ±0.004 mm accuracy
• Suitable for blind-hole measurements and RB6 output

Precise measurement where repeatability matters

The instrument combines a three-point measuring system with a high-resolution digital readout to reduce centring errors and provide consistent results in serial checks. With a display resolution of 0.001 mm and a stated accuracy of ±0.004 mm, this tool offers the kind of repeatability required for quality control in small-bore applications. The integrated RB6 data connection facilitates transfer of measured values into logging systems or SPC workflows, supporting measurable process stability and audit-friendly documentation.

Compact handling for blind-hole and small-bore inspection

Engineered for confined spaces, the micrometer’s measuring range 10–12 mm and compact form factor make it suitable for work on fine components and recessed bores. The geometry and three-point contact ensure a centred reading even in blind-hole situations, where conventional two-point probes can misalign. The instrument’s user controls — ON/OFF/SET, HOLD and mm/inch toggles — simplify operation under the bench lamp, enabling quick decisions during first-article inspection or in-process checks without sacrificing precision.

Built for the workshop — dependable and easy to integrate

At approximately 0.7 kg and with a practical overall length of 45 mm, this micrometer balances rigidity with manoeuvrability; handling is straightforward while stiffness helps to maintain measurement integrity. The design supports frequent use in production environments and benefits from Metav IndustryLine’s distribution and quality assurance: a reliable logistics and quality filter based in Emmerich ensures consistent availability and clear traceability for professional users who require trustworthy metrology equipment.

How the three-point system and digital features improve workflow

The three-point contact stabilises the probe within the bore and averages out minor eccentricities, producing a single centred value without complex alignment procedures. The digital interface not only shows readings in mm or inch but, via the RB6 output, enables collection of data for statistical evaluation or batch documentation. For precision technicians the combination of sub-micron display steps and robust mechanical centring translates into fewer re-measurements, faster set-ups and a measurable reduction in inspection time per part.
