Digital three-point internal rapid gauge M312.347 — 50–100 mm, 0.005 mm accuracy (Metav IndustryLine)

The Digital three-point internal rapid gauge M312.347 is a compact, workshop-focused instrument set for fast, traceable internal diameter checks and blind‑hole inspections in the 50–100 mm range.

• Digital three-point internal gauge set
• 50–100 mm measurement range
• 0.005 mm accuracy for precise control
• Rotating display 330° & RB6 + Bluetooth

Faster inspection for blind holes and bores

The three‑contact measuring concept delivers repeatable centring inside bores and blind holes, reducing setup time compared with single‑point probes. With a usable range of 50–100 mm, the set bridges gauge sizes commonly required in component assembly and maintenance. The rapid measuring heads are designed for quick interchange, which shortens measurement cycles and keeps throughput high on the shop floor. The instrument’s form factor supports stable engagement in confined bores, so measurements are both reliable and efficient.

Traceable readings and seamless data capture

Electronic readout with a resolution of 0.001 mm captures small deviations reliably; combined with a specified accuracy of 0.005 mm, this allows tight tolerance verification in production‑level quality control. The digital display offers ON/OFF, SET, CAL, INC, PRESET, HOLD, mm/inch and TOL functions for immediate adaptability to inspection tasks. Integrated RB6 output and Bluetooth enable direct data transfer to SPC systems or mobile devices, reducing transcription errors and speeding reporting. Battery operation uses a 3 V CR2032, ensuring simple field replacement and long service intervals.

Ergonomics and workshop practicality

A 330° rotating display keeps readings visible regardless of measuring orientation, improving operator ergonomics and reducing measurement retries. The set is supplied complete with four interchangeable measuring heads and is delivered in a protective transport case to safeguard the instrument during storage and movement. At a practical weight for a complete kit, the set is robust enough for shop environments yet portable for bench or in‑machine checks. The compact design helps maintain steady contact force and repeatability during interior measurements.

Where this set adds value in production

Ideal for machine shops, tool rooms and assembly inspection stations, the set shortens inspection loops on blind‑hole bores, housings and fitted components. The combination of quick three‑point probing, high resolution and wireless data output supports inline or batch inspection strategies and simplifies integration into digital quality workflows. Backed by Metav IndustryLine sourcing and distribution from Emmerich, the kit benefits from a dependable supply chain and a broad spare‑parts network for long‑term use.
