Measuring probe insert "Rubin" – Ø2 mm ruby ball, M2.5 thread (Metav IndustryLine)

A measuring probe insert "Rubin" for dial gauges, offering a Ø2 mm ruby contact ball on a 10 mm shank with an M2.5 connection for precise tactile measurements in inspection and workshop environments

• Ruby contact ball Ø2 mm
• M2.5 thread compatibility
• Compact 10 mm shank

Repeatable contact geometry for reliable results

A consistent contact tip is the foundation of repeatable comparative measurement. The ruby ball contact provides a hard, smooth surface that resists wear and preserves the original contact geometry over many inspection cycles, which improves repeatability and reduces the frequency of tip replacement. As a consequence, measurement results remain stable when checking small radii, grooves or centre points, and the defined Ø2 mm tip simplifies data interpretation for quality-control documentation. This compact contact geometry is particularly useful where a fine reference point is required without introducing additional probing deflection.

Compact design for quick fitting and versatile use

The insert’s 10 mm shank and standard M2.5 thread permit quick replacement on most dial gauges that accept an M2.5 connection, making the component a practical accessory in both production lines and inspection benches. The small overall dimensions keep the contact close to the gauge body, reducing bending moments during tactile inspection and aiding access in confined test setups. Lightweight construction (approx. 0.1 kg) helps maintain gauge balance and minimises operator fatigue during repeated checks. Where rapid swaps are required, the threaded connection ensures secure mounting and straightforward disassembly without specialised tools.

Efficient quality control through affordable, durable consumables

Using a wear-resistant ruby contact reduces total inspection cost by extending service intervals and cutting downtime spent on tip changes. The insert is an economical spare part for routine maintenance of dial gauges and supports a predictable spare-parts strategy within the workshop. Together with careful selection of contact geometry, this approach enhances throughput while keeping uncertainty low in go/no-go checks and comparative measurements. For traceable processes, keeping consistent tip geometry across a batch of gauges simplifies internal audits and helps preserve measurement comparability across successive production runs.

FAQ

What material is the contact tip made of?
The contact tip is a ruby ball; the M208.197 insert uses this hard, wear-resistant material for long service life.

Which instruments fit this insert?
This insert fits dial gauges that accept an M2.5 connection thread; compatibility is ensured by the standard M2.5 mounting.

How is the insert mounted and removed?
The probe insert is screwed into the gauge’s M2.5 thread; the threaded connection provides secure fitting and straightforward removal without special tools.

Is this insert suitable for fine internal measurements?
Yes; the Ø2 mm ball gives a small, well-defined contact point suitable for measuring small features, grooves and radii with minimal influence on the contact surface.

Can this insert be used as a direct replacement across brands?
Where the gauge uses a standard M2.5 connection, the M208.197 insert is a compatible spare; checking thread form and gauge geometry is recommended for full interchangeability
