The Asimeto 101 Series Manual Outside Micrometer is a purpose-built precision tool for machinists, inspectors, and calibration labs that need dependable external dimension measurements in the 75–100 mm range. Built for daily use in workshops, it combines robust construction with exacting tolerances to support consistent, repeatable results.

• Range: 75–100 mm outside measurement capability, ideal for checking larger parts, housings, flanges, and assemblies.
• Graduation: 0.01 mm main scale with 0.001 mm vernier resolution for fine, repeatable readings.
• Flatness and accuracy: Ultra-fine flatness specification (0.0000242 in / 0.6 μm) on the measuring faces to minimize errors across contact points.
• Measuring faces: Carbide-tipped contact surfaces deliver longer wear life and stable measurements over time.
• Frame material: Grey-painted steel frame provides durability and rigidity in demanding shop environments.
• Adjustment options: Optional ratchet stop and ratchet thimble help maintain consistent measuring force and reduce user variability.
• Included accessories: S-wrench, standard accessories for this range, plus warranty card, instruction manual, and calibration certificate.

This micrometer is designed to deliver reliable, high-precision readings with minimal drift. The carbide faces and rigid steel frame translate to longer usable life in busy workshops, while the optional ratchet features help ensure repeatable measurements, even when used by different operators. The calibration certificate provides traceability for quality systems, making it a solid choice for aftermarket manufacturing, machine shops, and metrology labs that require documented accuracy alongside everyday usability.
