Mitutoyo 103-135CAL Outside Micrometer 1 in Nist Cal

Product Description

The MITUTOYO 103-135CAL is a mechanical outside micrometer designed for precision dimensional measurement in shop, field, and inspection environments. It covers a 0 to 1 inch measurement range with a graduation of 0.0001 inches and an accuracy of plus or minus 0.0001 inches. The measuring faces and anvil are solid carbide for long service life and resistance to wear. A friction thimble provides consistent, repeatable measuring force, preventing operator-induced errors. This tool ships calibrated with NIST-traceable documentation, making it suitable for use in quality-controlled environments. Machinists, tool and die workers, pipefitters, and precision trade technicians are the primary users.

The 103-135CAL is used wherever an outside diameter, wall thickness, or flat stock dimension must be confirmed to the ten-thousandth of an inch. Typical applications include verifying shaft diameters, fastener dimensions, and machined part tolerances in manufacturing, maintenance, and inspection workflows. The included plastic case protects the instrument during storage and transport. Because this unit ships pre-calibrated with a NIST-traceable certificate, it is ready for immediate use in environments where documented measurement traceability is required by quality management systems.

Key Features

• 1 inch measurement range with 0.0001 inch graduation for high-resolution readings
• Accuracy of plus or minus 0.0001 inches for reliable dimensional verification
• Solid carbide anvil and measuring face for extended wear resistance
• Friction thimble ensures consistent measuring force and repeatable results
• Ships NIST-traceable calibrated with proprietary inspection certification included
• Hammertone baked enamel frame finish for corrosion resistance and durability

Compatibility

Designed as a standard outside micrometer for general-purpose dimensional measurement applications requiring a 0 to 1 inch range. No specific system or equipment compatibility is stated by the manufacturer for this instrument.

Installation Notes

Outside micrometers require no installation but should be handled by qualified metrology or trade personnel familiar with precision measuring instruments. Before use, clean the measuring faces with a lint-free cloth and verify the zero setting against the reference standard. Store the instrument in its case away from heat sources and cutting fluids. Periodic recalibration intervals should follow your facility quality management plan or applicable industry standards.
