M208.420 Extension for Internal Fine Measuring Instrument — 1,000 mm (Metav IndustryLine)

The M208.420 extension for internal fine measuring instruments increases measuring depth for dial indicators and similar internal metrology setups, enabling reliable assessment of deep bores and cavities in a workshop environment.

• 1,000 mm measuring depth extension
• Compatible with series 208.425/426/428/429
• Robust construction for repeatable results
• Mass 1.4 kg for improved stability

Reach deeper bores with workshop-ready measuring depth

The 1,000 mm extension is designed to extend the measuring depth of internal fine measuring setups, making deeper bores and recessed features accessible without resorting to bespoke gauging fixtures. By adding length to the existing probe train, routine inspection tasks in maintenance, small-series production and toolroom work become more efficient. The extension is intended for use with dial indicators and precision internal gauges commonly found in metrology benches, translating extended reach into fewer instrument changes and faster set-ups.

Stable readings through deliberate mass and compatibility

With a mass of 1.4 kg, the extension adds useful inertia that reduces vibration and hand-induced oscillation during measurement, helping to secure repeatability in results. The component is matched to the mounting and interface geometry of the listed series, ensuring mechanical compatibility and minimal play at the coupling points. This stability supports consistent trial-to-trial comparisons and shorter measuring cycles, which is particularly advantageous where reproducible internal measurements are required for quality control.

Integrates into existing metrology workflows with minimal effort

The extension is delivered as a single, workshop-ready component that integrates directly into existing setups for internal measurement, avoiding the need for extensive retrofitting. Compatibility with the 208.425/426/428/429 series simplifies inventory management and tool selection, while the robust build addresses the practical demands of industrial use. For operations seeking to broaden their inspection envelope without investing in a new instrument suite, this extension offers a pragmatic, performance-focused option.

FAQ

Is the extension compatible with other dial indicator series?
The M208.420 is specifically designed for mechanical compatibility with series 208.425/426/428/429; using it with other series may require adapters or checks for mechanical fit.

What measurement improvement does the extension provide?
By adding a 1,000 mm extension, the M208.420 enables inspection of deep internal bores and recessed features that would otherwise be inaccessible with standard probe lengths.

How does the extension affect measurement stability?
The additional mass (1.4 kg) and precise coupling reduce vibration and improve repeatability, supporting stable readings when used with compatible dial gauges.

Is the extension suitable for shop-floor environments?
Yes, the M208.420 is built for workshop use and is intended to integrate into existing metrology workflows for routine and production checks.

Does the extension come calibrated?
Calibration information is not provided with the product data; calibration status should be confirmed separately if a calibrated delivery is required.
