Repeatable high-precision measurement for standard workshop tasks

This instrument is classified as a standard micrometer (100–300 mm), providing the best compromise between reach and stiffness for general mechanical and metalworking applications. The device delivers a resolution of 0.01 mm and a stated accuracy of 0.014 mm, which makes it well suited to routine quality checks and workshop set-ups where reproducibility matters. The integrated friction ratchet stabilises closing force so that each reading is taken under comparable contact conditions, reducing operator-induced scatter and speeding up inspection loops.

Flexible measuring geometry for varied component contours

Seven interchangeable measuring inserts are supplied to adapt the contact geometry to shafts, grooves and stepped features without the need for separate micrometers. Changing inserts permits targeted contact shapes while keeping a single calibrated frame in service, which simplifies inventory and reduces tool-change downtime. The non-rotating measuring spindle minimises surface marking on sensitive parts and, together with the 6.5 mm spindle diameter, provides a rigid contact interface that supports stable, repeatable readings even on slightly irregular surfaces.

Robust construction aimed at daily industrial use

The measuring body combines a painted frame with a matt chrome-plated measuring drum, blending corrosion protection with a low-reflective, easy-to-read scale surface. A clear, mechanical thimble and vernier layout allow analogue reading at the specified resolution, avoiding dependence on batteries or electronics in harsh environments. At approximately 1.7 kg, the tool balances solidity and manoeuvrability for single-person handling during routine shop-floor checks and fixture set-ups.

Practical inclusions that speed up measurement tasks

Included accessory pairs of special measuring inserts expand the application range immediately after commissioning, while the factory-standard conformity ensures consistent production behaviour across batches. The unit is identified by SKU M309.087 and GTIN 4054469117911, enabling easy integration into asset registers and inspection protocols. For workshops seeking dependable metrology that aligns with everyday production rhythms, this micrometer offers a pragmatic mix of durability, adaptability and measured precision.

FAQ

What measuring range does this micrometer cover?
The Uni. Micrometer M309.087 covers a measuring range of 175–200 mm, placing it in the standard workshop category for general machine‑building and metalworking tasks.

How accurate and precise is the instrument?
The micrometer offers a reading resolution of 0.01 mm and a specified accuracy of 0.014 mm, making the M309.087 suitable for repeatable dimensional checks in production and inspection routines.

Are different contact shapes available for special components?
Yes, the M309.087 is supplied with seven pairs of interchangeable measuring inserts to adapt contact geometry for shafts, grooves and stepped features without changing the whole instrument.

Does the spindle rotate during measurement?
No, the measuring spindle is non‑rotating, which reduces the risk of marking delicate surfaces and contributes to stable contact during measurement.
