Mitutoyo 547-520S Electronic Thickness Gage

Product Description

The MITUTOYO 547-520S is a handheld electronic thickness gage designed for precise, non-destructive thickness measurement of sheet materials, films, gaskets, and similar workpieces. It measures from 0 to 12mm with a resolution of 0.01mm and an accuracy of 0.001 inches, delivering reliable repeatable readings in shop, lab, and field environments. The gage uses Digimatic technology with an Absolute (ABS) linear scale, which means the display retains its last position on power-up without requiring a return to zero. A grip handle and 1.5 N measuring force make single-hand operation practical for high-volume inspection tasks. Machinists, quality control technicians, and precision fabricators are the primary users.

The 547-520S is suited for measuring the thickness of thin materials where consistent, low contact force is critical to avoid deforming the workpiece. Typical applications include incoming inspection of sheet metal, plastic film, rubber gaskets, and printed circuit board substrates. The ceramic anvil face and flat contact geometry provide stable, repeatable contact on flat parallel surfaces. The waterproof data output connector and SPC output capability allow integration with data collection systems for statistical process control workflows in manufacturing environments.

Key Features

• Absolute (ABS) linear scale retains position on power-up, eliminating the need for origin reset after each startup
• Digimatic SPC output connector enables direct data transfer to compatible data collection systems
• Ceramic anvil face resists wear and corrosion for long service life in industrial environments
• 1.5 N measuring force minimizes deformation of soft or delicate materials during measurement
• Waterproof data output connector protects connectivity in wet or coolant-exposed environments
• Includes SR44 battery for immediate out-of-box use

Compatibility

Designed as an OEM-style handheld thickness gage compatible with Mitutoyo Digimatic SPC data collection systems and cables that accept standard Digimatic output.

Installation Notes

The 547-520S requires no permanent installation and is operated as a handheld instrument. Before use, verify the anvil and spindle faces are clean and free of debris to ensure accurate contact. When connecting to an SPC data collection system, use only compatible Digimatic interface cables and follow the data logger manufacturer guidelines for proper signal handling. Calibration verification against a certified reference standard is recommended before beginning a measurement run.
