Mitutoyo 103-145-10 Outside Micrometer 200-225mm

Product Description

The MITUTOYO 103-145-10 is an outside micrometer designed for precise external dimensional measurement in the 200 to 225mm range. It delivers a resolution of 0.01mm with finer 0.001mm capability, making it suitable for high-accuracy metrology work in machine shops, manufacturing facilities, and precision inspection environments. The frame features a hammertone, baked enamel finish for durability and comfortable handling. Carbide measuring faces extend service life under repeated use. A ratchet thimble promotes consistent measuring force, reducing operator-to-operator variation. Licensed machinists, quality technicians, and tool-and-die professionals are the primary users of this instrument.

This outside micrometer is applied wherever precise external measurements between 200 and 225mm are required. Typical use cases include inspecting turned parts, shafts, flanges, and machined components on the production floor or in a quality lab. The included standard bar allows for calibration verification at the nominal range. The ratchet thimble is especially useful in production environments where multiple operators use the same instrument, ensuring repeatable contact pressure across measurements.

Key Features

• Measuring range: 200 to 225mm
• Resolution of 0.01mm with 0.001mm finer graduation
• Carbide measuring faces for extended wear resistance
• Hammertone, baked enamel finished frame for durability and grip
• Ratchet thimble for consistent, repeatable measuring force
• Includes standard bar for range verification and calibration checks

Compatibility

Designed as a standard outside micrometer for use in precision measurement applications requiring a 200 to 225mm external measurement range.

Installation Notes

Outside micrometers require no installation but should be handled and stored by a qualified metrologist or technician familiar with precision hand tools. Before use, verify the instrument against the included standard bar and adjust the zero reference as needed. Store the micrometer in its case away from heat, moisture, and direct contact with other tools to protect the measuring faces and frame finish. Never force the thimble — use only the ratchet stop to engage the measuring faces against the workpiece.
