Mitutoyo 103-144-10 Mechanical Outside Micrometer

Product Description

The MITUTOYO 103-144-10 is a mechanical outside micrometer built for precise linear measurement in workshop and field environments. It features a 0.01-inch graduation and a stated accuracy of 0.0001 inches (4 micrometers), making it suitable for close-tolerance inspection work. The solid carbide anvil and measuring face resist wear during repeated use. A ratchet stop thimble delivers consistent measuring force, reducing operator-to-operator variation. The frame carries a hammertone baked enamel coating and is designed around a lightweight workshop form factor. A standard bar is included for calibration verification. Licensed metrology technicians, machinists, and quality-control personnel are the primary users.

This outside micrometer is suited for dimensional inspection of external workpiece features in manufacturing, maintenance, and quality-assurance settings. The ratchet stop thimble makes it a practical choice for production environments where multiple operators share the same instrument and repeatable force application is critical. The lightweight frame reduces fatigue during extended inspection sessions. The 103-144-10 is intended for bench and shop use where a mechanical, non-digital instrument is preferred or required by process documentation.

Key Features

• 0.01-inch graduation for fine linear measurement resolution
• Accuracy of 0.0001 inches (4 micrometers) for close-tolerance inspection
• Solid carbide anvil and measuring face for extended wear resistance
• Ratchet stop thimble for consistent, repeatable measuring force
• Hammertone baked enamel frame coating for durability and grip
• Includes standard bar for on-site calibration verification

Compatibility

Designed as an OEM-style mechanical outside micrometer for general external dimensional measurement applications in workshop and quality-control environments.

Installation Notes

Outside micrometers require no permanent installation. Before use, verify calibration with the included standard bar and zero the instrument per standard metrology practice. Keep the measuring faces clean and free of debris before each measurement. Store the micrometer in its case with the anvil and spindle faces not in contact to prevent thermal expansion errors and surface damage.
