Mitutoyo 513-482-10A Horizontal Dial Test Indicator

Product Description

The MITUTOYO 513-482-10A is a horizontal dial test indicator designed for precision measurement in machine shops, tool rooms, and on the production floor. It reads from 0 to 0.03 inches with a dial graduation of 0.0005 inches, making it well-suited for checking runout, flatness, and part alignment where tight tolerances are critical. The 40mm white dial provides a glare-free, high-contrast reading surface. The indicator features a no-clutch structure with automatic reversal, a carbide-tipped contact point, and an O-ring sealed, dust and oil proof housing built for industrial environments. Machinists, metrologists, and precision technicians are the primary users.

This horizontal-style test indicator is used in setups where the stylus must approach the work surface from the side rather than from above, such as when indicating bores, inside diameters, or features that are inaccessible to a plunger-type indicator. It is equally at home on a surface plate, mounted in a magnetic base, or held in a machine spindle for runout checks. The 0-15-0 balanced dial reading makes bidirectional deviation easy to read at a glance. Suitable for both production inspection and general setup work in machining, fabrication, and quality control environments.

Key Features

• 0 to 0.03 inch range with 0.0005 inch graduation for fine-tolerance measurement
• Balanced 0-15-0 dial layout allows easy bidirectional deviation reading
• 40mm white dial with glare-free, scratch-resistant crystal for clear sightlines
• Carbide-tipped contact point with 0.079 inch ball diameter for durability
• No-clutch automatic reversal mechanism reduces wear and maintenance
• Dust and oil proof construction with O-ring seal for industrial use
• High-impact resistant housing suited for shop floor conditions

Compatibility

Designed as a standard horizontal dial test indicator compatible with universal magnetic bases, indicator holders, and transfer stands that accept industry-standard dovetail or stem mounting configurations.

Installation Notes

Horizontal dial test indicators are typically set up and used by machinists, quality technicians, and metrologists. Secure the indicator firmly in a compatible holder or magnetic base before use to prevent measurement error from vibration or slippage. Avoid overloading the stylus beyond its rated travel range, as forcing the mechanism can damage the movement. When not in use, store the indicator in its case away from moisture, shock, and extreme temperatures to preserve calibration.
