M208.021 Internal Fine Measuring Gauge 18–35 mm, 0.01 mm dial (Metav IndustryLine)

The M208.021 Internal Fine Measuring Gauge is an analogue precision instrument for interior diameter checks and workshop inspection tasks, designed for compact, repeatable measurements in small-bore applications.

• Analogue 0.01 mm resolution dial
• Repeatability 0.005 mm
• Measuring range 18–35 mm

Precision where it counts for quality control

The instrument offers an analogue dial with a readable increment of 0.01 mm, combined with a documented repeatability of 0.005 mm. This pairing ensures that routine internal measurements remain consistent between operators and over multiple cycles, improving process control and reducing scrap. Clear mechanical feedback from the dial supports quick decision making on the shop floor while preserving traceable measurement quality for inspection records.

Compact internal measurement capability for fine components

With a measuring span of 18–35 mm, the device classifies as a micro internal gauge suited to finely machined bores and small assemblies where accessibility and stiffness are essential. The set includes nine interchangeable pins (M4x4.5) covering nominal steps from 18 mm to 34 mm, allowing flexible set-up for a range of small diameters without the need for large fixture changes. The modular pin concept shortens changeover times and helps maintain consistent contact geometry during series checks.

Robust build and transport protection for workshop use

The holder is matt chrome-plated, providing corrosion resistance and a hard-wearing surface that stands up to daily workshop use. The gauge has a measured depth capability of 150 mm, enabling evaluations of recessed features and stepped bores. Delivered in a protective case for secure transport, the instrument arrives ready for integration into inspection benches or portable measuring kits, combining a compact footprint with the physical robustness required for frequent handling.

Integrating the gauge into inspection workflows

Thanks to its mechanical design and simple set of interchangeable measuring pins, the instrument supports fast in-line checks and periodic quality verifications. The repeatability figure and the fine dial increment allow the device to catch small deviations early in the process, driving more efficient corrective actions and fewer downstream defects. Lightweight at 0.65 kg, the gauge is practical for mobile inspection rounds while retaining the stiffness needed for reliable short-range internal measurements. The M208.021 therefore serves as an effective first-line tool for workshops and quality departments seeking dependable, reproducible internal measurements.
