Mitutoyo 145-195 Mechanical Caliper Micrometer 2-3 in

Product Description

The MITUTOYO 145-195 is a mechanical caliper micrometer designed for precision outside measurement in the 2 to 3 inch range. It delivers a graduation of 0.001 inches and an accuracy of 0.000350 inches, making it suitable for high-tolerance inspection and machining verification work. The measuring faces are constructed from solid carbide for durability and wear resistance. The satin chrome finish reduces glare during use. This tool is intended for machinists, quality control technicians, and toolroom professionals who require repeatable, instrument-grade measurements without digital electronics.

The 145-195 is used in toolrooms, machine shops, and inspection departments where precise dimensional verification of turned, ground, or milled components is required. The 2 to 3 inch measurement range covers a common intermediate shaft, bore, and workpiece diameter class. Because this model requires a setting standard to accurately set the micrometer to its reference point, it is best suited for environments where a certified gage block or reference standard is available for calibration before use.

Key Features

• Measurement range from 2 to 3 inches
• Graduation of 0.001 inches for fine incremental readings
• Accuracy of 0.000350 inches for high-tolerance inspection
• Solid carbide measuring faces for extended service life
• Satin chrome finish minimizes surface glare
• Mechanical analog readout with no battery or digital components required

Compatibility

Designed as a standard outside micrometer for use in general toolroom and inspection applications within the 2 to 3 inch measurement range. A setting standard is required to accurately set this micrometer to its reference point prior to measurement.

Installation Notes

This instrument is handled and calibrated by metrology technicians or toolroom professionals, not installed in a mechanical system. Before use, the micrometer must be set to its reference point using a certified setting standard or gage block appropriate to the 2 to 3 inch range. Store in its protective case when not in use to prevent damage to the carbide measuring faces. Avoid dropping or impacts that could affect calibration.
