M208.414 interior precision gauge — 100–300 mm range with 10 mm dial (Metav IndustryLine)

The M208.414 is an analogue interior measuring instrument designed for accurate internal dimension checks in metalworking and general workshop quality control, featuring a long measuring depth and a fine 10 mm dial for clear incremental readings.

• Large measuring range 100–300 mm
• High resolution 0.01 mm dial reading
• Repeatability 0.005 mm for consistent checks
• Matt chrome-plated holder for durability

Precision where reach and resolution matter

This interior gauge combines a 100–300 mm measuring range with a 10 mm dial that provides a clear 0.01 mm resolution, making it suitable for the workshop standard class of internal gauges. Classified in the standard range for machine and metalwork measurement, it offers a practical balance between reach and stiffness: the long jaw length supports measurements of medium-sized bores and housings while retaining ease of handling. The instrument’s repeatability of 0.005 mm ensures repeat measurements remain consistent, so process control and routine inspections can be performed with confidence.

Stable construction for reproducible measurements

Built around a matt chrome-plated device holder, the gauge is engineered for stable contact and minimal flex during probing. The 250 mm measuring depth extends access into deeper features without sacrificing support for the measuring posts; six measuring pins (Ø8 mm) distribute contact forces and reduce point loading on the workpiece. Extensions of 50 mm and 100 mm are available to increase effective reach for larger components. Delivered in a protective case for safe transport, the unit’s design focuses on repeatable readings and long service life in industrial environments.

Straightforward operation with industrial applicability

Operation is carried out via the analogue dial and sliding beam, allowing rapid incremental readings on the dial while the beam covers the full range. This familiar mechanical principle minimises setup time in production or inspection routines and avoids reliance on batteries or electronics. The gauge is ideal for routine internal checks, fixture set‑up verification and incoming part inspection where clear, tactile feedback and mechanical robustness are preferred. Its attributes make it a practical tool for workshops seeking reliable internal measurement without complex data management.

FAQ

What resolution and repeatability does this interior gauge offer?
The M208.414 provides a dial resolution of 0.01 mm and a stated repeatability of 0.005 mm, suitable for precise workshop inspections.

Is the instrument suitable for deeper internal features?
Yes — with a 250 mm measuring depth and available extensions (50 mm and 100 mm), the gauge allows access to deeper bores and cavities while maintaining stable support.

What is included for transport and protection?
The instrument is supplied in a protective case for transport and safe storage; the delivery also includes gauge shims (1, 2, 3, 5) and the measuring pins referenced in the technical data.

Can this analogue gauge be used for routine incoming inspection in a metalworking shop?
Absolutely — its combination of 100–300 mm range, 0.01 mm dial resolution and 0.005 mm repeatability makes it well suited for standard workshop quality control and fixture checks.

How are longer reaches achieved if required?
Longer effective reach is achieved using the supplied or optional 50 mm and 100 mm extensions, extending the instrument’s applicability to larger components.
