Uni. Micrometer M309.172 — 50–75 mm, 0.01 mm resolution (Metav IndustryLine)

The Uni. Micrometer M309.172 is an analogue inspection micrometer designed for accurate external measurements in workshop and inspection environments across a 50–75 mm range.

• High precision 0.01 mm graduation
• Movable anvil for adaptable measuring depths
• Ratchet stop for consistent measuring force
• Includes 7 pairs measuring inserts

Reliable precision for quality control

The Uni. Micrometer M309.172 delivers 0.01 mm graduation combined with a robust 6.5 mm spindle, offering a solid foundation for repeatable external measurements. The integrated ratchet stop limits operator-applied force, which improves reproducibility and reduces wear on the spindle tip — a pragmatic advantage during series inspection. As an analogue instrument, it provides direct tactile feedback that many technicians prefer for fine adjustment and verification tasks. This configuration supports routine quality checks and first-article inspection in small-batch production.

Flexible handling for varied workpieces

A movable anvil broadens the range of geometries that can be checked without additional tooling, while the supplied 7 pairs of measuring inserts make the instrument ready for different contact profiles straightaway. The matt chrome-plated measuring drum reduces glare and improves scale readability under workshop lighting. These features combine to shorten setup time and increase throughput: fewer tool changes are required and measurements can be completed with steady hand positioning. The instrument’s balance and finish also aid comfortable, controlled operation during repetitive measurement cycles.

What is supplied and how to care for it

Delivery includes the micrometer fitted with the rotating spindle and ratchet stop plus 7 pairs of measuring inserts and a protective case for transport and storage. The unit is manufactured to factory standard (Werksnorm) and is supplied ready for immediate use; routine care — keeping faces clean, protecting against knocks, and storing in the case after use — prolongs service life and maintains accuracy. The analogue scale is straightforward to interpret and, when required, the instrument can be referenced against traceable standards to integrate into a formal inspection routine.
