Three‑point internal micrometre (6–8 mm) — Metav IndustryLine, 0.005 mm accuracy

The Three‑point internal micrometre is a compact, self‑centring measuring instrument designed for precise internal diameter measurement in fine mechanical, toolmaking and inspection environments.

• Self‑centring three‑point measuring contact
• Resolution 0.001 mm for fine readings
• Accuracy ±0.005 mm for repeatable results
• Carbide measuring faces for wear resistance

Reliable measurement performance for inspection tasks

The analogue three‑point internal micrometre delivers a resolution of 0.001 mm and an accuracy of ±0.005 mm, enabling high‑precision checks where small deviations matter. The mechanical readout provides immediate visual feedback without electronic interfaces, which simplifies routine inspection procedures and reduces potential integration overhead. These numeric specifications support traceable decisions in quality control and enable consistent acceptance criteria across batches.

Compact design tailored to micro‑work

Classified in the micro range (measuring span 6–8 mm), this instrument is optimised for very small bores and delicate components where stability and centring are critical. The self‑centring three‑point contact ensures the measuring anvils align automatically with the bore, reducing operator influence and improving repeatability for tight‑tolerance parts used in watchmaking, miniature hydraulics or precision fittings. The narrow span and robust geometry make handling straightforward while preserving measurement integrity.

Built for durability and repeatable use

Critical wear areas are fitted with carbide measuring faces, which resist abrasion and extend service life under frequent use. The analogue mechanical construction minimises electronic failure modes and simplifies maintenance routines. For secure transport and protection, the micrometre is supplied in a protective case suitable for workshop traffic, helping to preserve calibration and surface quality during storage and transit.

Practical integration into workshop workflows

As a standardised inspection tool, the instrument fits established measurement routines and complements conventional gauging sets. Its clear numeric capability supports fast go/no‑go assessments and documentation of small internal diameters. Metav IndustryLine positions this micrometre within a wider portfolio of precision instruments, offering a reliable supply chain and product consistency that benefits laboratories and production environments seeking reproducible measurement outcomes.
