Mitutoyo 523-131 Mechanical Outside Micrometer 0-1 in

Product Description

The MITUTOYO 523-131 is a mechanical outside micrometer designed for precise linear measurement of external dimensions. It covers a measurement range of 0 to 1 inch with a graduation of 0.00005 inches and an accuracy of 0.000050 inches, placing it in the class of high-resolution hand tools used for critical dimensional inspection. The spindle and anvil measuring faces are solid carbide for durability and wear resistance. A friction thimble provides consistent measuring force, reducing the chance of over-tightening and protecting workpiece surfaces. The satin chrome finish reduces glare under shop lighting. This tool is used by machinists, quality control technicians, tool and die makers, and precision manufacturing professionals.

The 523-131 is suited for dimensional inspection tasks in machine shops, manufacturing facilities, and quality assurance environments. It is used wherever a 0 to 1 inch outside measurement must be taken with high resolution. The friction thimble design makes it appropriate for operators who need repeatable force application across multiple measurements. An easy-to-operate retracting button simplifies part insertion and speeds up workflow. The tool ships with a plastic storage case to protect the measuring surfaces when not in use.

Compatibility

Designed as a standard 0 to 1 inch range outside micrometer suitable for general-purpose external dimensional measurement applications in machine shop and quality control settings.

Installation Notes

Outside micrometers do not require installation in the traditional sense but should be calibrated against a known standard before use, particularly after storage or transport. Clean the measuring faces with a lint-free cloth before taking measurements. Store the tool with a slight gap between the anvil and spindle to allow for thermal expansion. Calibration and maintenance should be performed by a qualified metrologist or tool room technician following the manufacturer's guidelines.
