The Insize 3210 Outside Micrometer delivers precise external measurements with a tight 0.001 mm graduation and a generous range up to 200 mm. Built for engineers, machinists, and workshop professionals, it provides reliable, repeatable readings for components like shafts, pins, and fitted parts where tight tolerances matter. Its robust design makes it a dependable companion in QC labs, machine shops, and field work alike.
- 0.001 mm Graduation: Delivers fine, high-resolution readings for accurate verification of small tolerances and close-fitting parts, helping you confirm part-to-part consistency quickly.
- Carbide Measuring Faces: Hardened, wear‑resistant surfaces resist deforming and wear, preserving measurement accuracy through heavy use and repeated checks.
- Includes Setting Standards: Supplied with setting standards for fast calibration and traceable reference checks—except for the 0–25 mm size, so you can trust measurements out of the box.
This micrometer supports streamlined workflows by delivering dependable results with minimal setup. Its wide 200 mm range reduces tool swapping in busy environments, while the durable carbide faces maintain precision over time. With ready-to-use calibration references and a proven measurement resolution, it helps improve inspection speed, ensure tighter tolerances, and maintain consistent quality across production and assembly tasks.
