A precision workshop measuring tool that promises repeatable external measurements to 0.01mm, ideal for inspection and setup. Confidence when checking tolerances and setting fixtures, helpful for machinists and keen hobbyists. Is Proster Outside Micrometer accurate and robust enough for routine professional use?
⚡ At a Glance
- • Measurement Accuracy: Guaranteed 0.01mm accuracy across a 0-25mm measuring range
- • Best for: Beginners, hobbyists and professional machinists needing precise external measurements
- • Not ideal for: Measuring internal diameters or components larger than 25mm
0-25mm range with 0.01mm graduations and engraved scales, designed for repeatable external measurement. Tungsten-carbide measuring surface, satin-finished chrome thimble and a locking mechanism are included for workshop durability.
Consistent, repeatable readings - thanks to 0.01mm graduations and engraved scales
Graduated thimble and barrel include 0.01mm markings with a locking mechanism for repeated measurements, while a special wrench allows straightforward zero adjustment and calibration.
Accurate repeatability speeds up inspection tasks and reduces rework, making measurements reliable for both training and production.
Durable contact surfaces - with tungsten-carbide measuring faces
The largest measuring surface is made from tungsten carbide steel, a material chosen for high wear resistance under repeated contact.
Long-term maintenance of accuracy means fewer replacements and stable readings in busy toolrooms and workshops.
Easy reading and handling - thanks to satin-finished chrome thimble and contrasting scales
Satin finish reduces glare and the black contrasting scales on the thimble and barrel improve legibility, supported by an engraved scale layout for quick reference.
Faster, less error-prone readings help both newcomers and experienced users work more efficiently at the bench.
