Mitutoyo 505-742-52JCAL Dial Caliper 6 Inch Nist

Product Description

The MITUTOYO 505-742-52JCAL is a 6-inch dial caliper machined from stainless steel and designed for precise dimensional measurement in trade and industrial settings. It delivers an accuracy of plus or minus 0.001 inches with a dial graduation of 0.001 inches, making it suitable for exacting quality-control and layout work. The dial face is purple for easy reading, and a lock screw holds the dial measurement in place during inspection. This caliper ships with a NIST traceability certification and a proprietary inspection certificate, confirming it has been verified against national measurement standards before leaving the factory.

This caliper is used by machinists, pipefitters, HVAC fabricators, plumbers, and precision tradespeople who need reliable measurements on the bench or in the field. It handles outside, inside, depth, and step measurements in a single tool, covering the most common dimensional tasks encountered during fabrication, fitting, and quality inspection. The 40 mm jaw length accommodates a wide range of workpiece geometries. It is equally at home in a machine shop, a sheet-metal fabrication bay, or a mechanical contractor's service van.

Key Features

• Accuracy of plus or minus 0.001 inches for precise dimensional checks
• Measures outside, inside, depth, and step dimensions in one tool
• Stainless steel body and jaws resist corrosion and wear in shop environments
• Purple dial face with 0.001-inch graduation for clear, fast readings
• Lock screw secures the dial reading while recording or transferring measurements
• Includes NIST traceability certification and fitted plastic case

Compatibility

Designed as a general-purpose dial caliper for use in any trade or industrial application requiring precise inch-system measurements up to 6 inches.

Installation Notes

Dial calipers require no installation but should be handled and stored with care to preserve calibration. Keep the sliding jaw clean and free of metal chips, cutting fluid, and debris before and after each use. Store the caliper in the included fitted plastic case when not in use to protect the dial and beam. Verify the caliper reads zero at full closure before beginning any measurement series; if zero drift is observed, the instrument should be recalibrated before use.
