Three-point internal micrometer — digital display, measuring range 150–175 mm (Metav IndustryLine)

The three-point internal micrometer is a digital instrument for fast, repeatable internal-diameter checks in machine and metalwork applications.

• Digital display with mm/inch and hold
• High repeatability: accuracy ±0.007 mm
• Delivery in protective case

Reliable precision for everyday workshop inspection

The instrument delivers accuracy ±0.007 mm, which places it well within fine inspection tolerances for many production and quality-control tasks. With a measuring range 150–175 mm it fits the Standard class of calipers and micrometres, the length band that balances reach and stiffness for general machine‑ and metal‑shop use. The stated accuracy means a measurement scatter in the single‑digit micrometre range; this reduces rework and supports consistent part acceptance criteria without requiring complex measurement rigs.

Digital features that speed up measurement and reduce errors

Equipped with a digital display and the full set of ON/0-, mm/inch, ABS, PRESET and HOLD functions, the device simplifies data capture and reduces transcription mistakes during batch checks. The built‑in RB 4 data output enables wired transfer of readings to a data logger or inspection software, supporting traceable records and faster statistical process control. PRESET allows quick zeroing for comparative checks, while HOLD freezes unstable readings for later recording — practical when handling larger specimens or awkward positions.

Robust design and transport-ready delivery

Hardened contact points ensure long service life under shop conditions: the instrument features hardened measuring faces that resist wear from repeated contact. A measuring depth 140 mm gives access to recessed bores and deeper features without compromising rigidity. Delivery in a protective case helps prevent damage during transport and storage; note that the scope of delivery is without a setting ring, so calibration or a reference standard should be arranged separately if required before first use.

Practical fit for inspection benches and toolrooms

This digital three‑point internal micrometer is a practical choice for inspection benches, assembly control and first‑off checks where internal diameters must be verified quickly and reliably. The combination of a Standard measuring range and a clear digital interface makes the instrument suitable for toolmakers, quality engineers and maintenance teams who need dependable results with minimal setup. The compact three‑point measuring head aligns automatically in bores, reducing operator influence on repeatability and simplifying measurements on cylindrical components.
