Description

The Insize 3210 Series outside micrometer delivers precise external measurements with a fine 0.001 mm graduation. Its compact, ergonomic green frame and knurled thimble provide confident handling and repeatable readings for engineers, machinists, technicians, and hobbyists. With a measuring range up to 200 mm, it covers a wide spectrum of common parts without switching tools.

Equipped with carbide measuring faces, the micrometer resists wear and maintains accuracy after many measurements. Supplied with setting standards (except 0-25 mm), it offers quick, reliable reference points for zeroing and checks, helping you minimize drift and rework.

  • 0.001 mm Graduation: Delivers high-resolution readings for close tolerance checks and small dimensional changes, enabling tighter quality control and more consistent results.
  • Carbide Measuring Faces: Built to resist wear and maintain flatness, providing durable, long-lasting accuracy even with harder or rougher parts.
  • Includes Setting Standards (except 0-25 mm): Facilitates fast, reliable setup and drift-free verification right out of the box, reducing calibration downtime.

Together, these features translate to faster measurement workflows, fewer repeats, and more dependable results in production, inspection, and repair environments. The broader 200 mm range reduces tool swapping, while the durable construction and high-precision graduation ensure consistent readings you can trust across daily tasks.
