Uni. Micrometer M309.085 – 125–150 mm, 7 interchangeable measuring inserts, friction ratchet (Metav IndustryLine)

The Uni. Micrometer M309.085 is a robust outside micrometer for workshop and quality‑control use, covering the standard 125–150 mm range and supplied with seven pairs of special interchangeable measuring inserts for flexible contact geometries.

• Precise range 125–150 mm
• Seven interchangeable measuring inserts
• Friction ratchet for consistent force

High precision where it matters

This workshop micrometer delivers a verified accuracy of ±0.012 mm and a reading resolution of 0.01 mm, making it suitable for demanding routine checks in metalworking and assembly. The combination of a fine‑graduated scale and a stable mechanical spindle gives a reproducible result cycle after cycle; the numerical tolerances state the expected measurement uncertainty, which supports traceable inspection workflows and reduces rework costs.

Flexible measuring options with rapid changeovers

Equipped with seven pairs of interchangeable measuring inserts, the instrument adapts quickly to different contact forms without compromising repeatability. The insert system simplifies checks on shafts, steps and bore seats by matching the contact geometry to the component. For production environments that handle mixed batches, this flexibility shortens setup time and increases throughput while keeping measurement quality consistent.

Designed for repeatable handling and durability

The micrometer features a friction ratchet that enforces a constant closing force and a non‑rotating 6.5 mm spindle, which together reduce operator‑induced variation. The frame is finished with a painted surface and the measuring drum is matt chrome‑plated for glare reduction and corrosion resistance. At around 1 kg, the instrument balances solidity and manageability for bench use; the ergonomic design supports steady hand positioning during repeated measurements.

Ready for workshop use and secure transport

Delivered with a setting gauge and the seven pairs of inserts, the micrometer is supplied ready for immediate use and protected in a transport case for safe handling. The device conforms to the manufacturer's Werksnorm and carries the model identification M309.085, making it straightforward to reference in inspection records. For workshops seeking a reliable standard‑range micrometer, this instrument offers a pragmatic balance of accuracy, adaptability and robustness.

FAQ

Is the micrometer supplied ready for measurement? Yes. The Uni. Micrometer M309.085 is delivered with a setting gauge and seven pairs of special measuring inserts so it can be put straight to use.

What accuracy and resolution can be expected? The instrument provides a resolution of 0.01 mm and an accuracy of ±0.012 mm as stated for the model M309.085.

Can different contact geometries be used for shafts and steps? Yes. The seven interchangeable measuring inserts included with the micrometer allow adaptation of the contact geometry for shafts, steps and similar features.

How does the friction ratchet help in daily use? The friction ratchet enforces a consistent closing force, reducing variability between operators and improving repeatability during repetitive checks with the micrometer.

Is the spindle design intended to improve measurement stability? The non‑rotating 6.5 mm spindle reduces surface‑induced errors and, together with the robust frame, helps maintain stable readings during routine inspections.
