The 0-100mm Digital Outside Micrometer Set from the 3109 Series delivers precise outside measurements with a clear digital readout, making it ideal for machinists, inspectors, and workshop professionals who value speed and reliability.

  • Measuring range: 0–100 mm outside measurement, designed for everyday machining and inspection tasks in tight spaces.
  • Resolution: 0.001 mm (0.00005 in) for quick, repeatable readings with fine detail where it matters.
  • Carbide measuring faces: hard-wearing faces that resist wear and maintain accuracy over time on a variety of materials.
  • Unit conversion: convenient mm/inch button to switch display units without re-zeroing, streamlining mixed-unit workflows.
  • ABS/INC and setup: supports Absolute and Incremental measurement modes with a dedicated set function for flexible use in different measurement scenarios.
  • Power and battery: LR44 battery with automatic power-off to extend battery life between uses and reduce downtime.
  • Included standards: Supplied with setting standards to facilitate fast, on-site calibration and verification.

With its digital readout, this micrometer minimizes parallax errors and speeds up calibration checks. The carbide faces provide durable, long-lasting performance on hardened workpieces, while the metric/imperial conversion and ABS/INC modes adapt to a wide range of measurement tasks. The compact case keeps the 0-100mm Digital Outside Micrometer Set organized for the shop floor or fieldwork, ready to deliver accurate measurements when precision matters most.
