Internal fine measuring instrument 250–450 mm — analogue dial, 500 mm depth (Metav IndustryLine)

The Internal fine measuring instrument 250–450 mm is an analogue gauge system designed for accurate internal diameter and bore measurements in machine construction and quality control.

• Measuring range 250–450 mm
• 500 mm measuring depth
• 0.01 mm resolution
• Repeatability 0.02 mm

Consistent precision for internal bores

This analogue gauge is built for repeatable, workshop-ready precision: the 0.01 mm resolution combined with a tested 0.02 mm repeatability makes it suitable for routine quality checks where consistent results matter. The dial readout is immediate and readable in typical shop lighting, reducing interpretation errors compared with less legible instruments. The extended measuring depth permits access to recessed features, so larger internal diameters can be assessed without multiple setups, improving throughput in production and inspection tasks.

Solid construction and practical handling

A matt chrome-plated device holder ensures robust corrosion resistance and a stable fixture for the gauge assembly, while a modest weight of 1.4 kg keeps the unit manageable for single-person operation. The tool includes measuring pins 5 x Ø8 mm and a set of gauge discs for secure seating; extensions (50 mm, 100 mm) are available to adapt the base range when deeper reach is required. These mechanical design choices prioritise stiffness and repeatability, which helps to limit measurement uncertainty arising from flexing or misalignment during use.

Designed for typical workshop and production tasks

Engineered for applications such as internal diameter checks, bore alignment and fixture verification, this internal gauge supports fast inspection cycles in machine shops and toolrooms. The combination of a wide measuring range 250–450 mm and 500 mm measuring depth reduces the need for frequent repositioning, accelerating part throughput. The analogue format suits environments where durability and immediate visual feedback are preferred over digital integration, while retaining industrial-grade accuracy for standard quality control.

FAQ

What internal sizes can be checked with this instrument?
The internal fine measuring instrument 250–450 mm from Metav IndustryLine covers diameters within the 250–450 mm range; with the supplied 500 mm measuring depth it can reach recessed bores within that span (SKU M208.426).

Is the readout fine enough for routine quality control?
Yes — the analogue dial offers 0.01 mm resolution and 0.02 mm repeatability, values that support standard machine‑shop inspection and process control.

Can the range be extended for deeper measurements?
Yes — extensions of 50 mm and 100 mm are available to reach greater depths while retaining the same measuring principles.

What materials and accessories are included or fitted?
The instrument features a matt chrome-plated device holder, comes with 5 x Ø8 mm measuring pins and a set of gauge discs (0.5 / 1 / 2 / 3 / 6 x Ø11); further accessories can be supplied on request.
