Mitutoyo 103-143-10 Mechanical Outside Micrometer

Product Description

The MITUTOYO 103-143-10 is a mechanical outside micrometer designed for precise linear measurement in machining, inspection, and quality control environments. It delivers an accuracy of 0.0001 inches (4.00 micrometers) with a graduation of 0.01 inches, making it suitable for tight-tolerance work. The micrometer features a ratchet stop thimble for consistent measuring force and a solid carbide anvil and measuring face for long-term wear resistance. A lightweight workshop design keeps fatigue low during extended use. A standard bar is included for reference calibration.

This outside micrometer is used in precision measurement applications across manufacturing, machine shops, tool rooms, and inspection departments. It is suited for measuring the outer dimensions of round stock, shafts, and machined parts where dimensional accuracy is critical. The lightweight construction makes it practical for bench use and field inspection alike. It is typically deployed by machinists, metrologists, and quality control technicians working to close tolerances.

Installation Notes

Outside micrometers require no power source and are handled by machinists or quality control technicians. Before use, zero the instrument against the included standard bar following the manufacturer calibration procedure. Keep the measuring faces clean and free of debris to maintain accuracy. Store in the provided case away from temperature extremes to prevent thermal expansion errors.
