SPI Coating Thickness Gage

The SPI Coating Thickness Gage can perform two different methods of calculating thickness measurement by utilizing the characteristics of both eddy current and magnetic induction

• Testing performance is both nondestructive and extremely accurate
• Sleek state of the art thickness gauge easily detects the thickness of nonmagnetic coating on a magnetic substrate (ferrous) or an insulating coating on a non-magnetic conductive substrate (non ferrous)
• Can be used in many Areas of industry including automative, manufecturing, general engineering, commercial inspection, etc
• Flip display for reading upside down
• Includes: unit, 2 substrate samples (Steel, Aluminium), 4 calibrated thickness samples, operation manual, batteries, and carrying case.
