The Insize 3203 Outside Micrometer, 200–225 mm (metric), is a compact, reliable tool for measuring external dimensions with confidence in busy workshops, labs, and job sites. It features a precise 0.01 mm graduation and durable carbide measuring faces, making it well-suited for repetitive use and demanding environments.

As part of Insize’s best-selling 3203 series, this micrometer is built for long life and repeatable results. It ships with setting standards (except 0–25 mm) to speed setup and maintain accurate measurements across shifting tolerances and varied materials.

  • 0.01 mm Graduation: Easy-to-read, fine graduations that deliver precise, repeatable measurements and reduce the risk of misreads during critical checks.
  • Carbide Measuring Faces: Hardened faces resist wear from everyday shop use, extending tool life and preserving accuracy even after heavy use.
  • Includes Setting Standards and Broad Range: Comes with setting standards for fast, reliable zeroing and calibration, with a size range that accommodates parts up to 300 mm for versatile applications.

This micrometer helps you streamline quality control, reduce downtime, and achieve consistent results across multiple parts and batches. With its precise graduation, durable construction, and quick-start setup, you can trust it to deliver dependable external measurements every time your project demands accuracy.
