Ketos Ring

The Ketos Ring is a precision-engineered reference standard used for evaluating the overall performance of a magnetic particle examination system. It serves as a crucial tool in Non-Destructive Testing (NDT), particularly in Magnetic Particle Inspection (MPI), by ensuring that magnetic field strength, particle sensitivity, and system functionality meet industry standards.

Manufactured from high-quality ferromagnetic steel, the Ketos Ring is designed with a 5-inch diameter, a thickness of 0.875 inches, and a central mounting hole of 1.25 inches. The 12 precision-drilled through-holes, each with a 0.070-inch diameter, are positioned at incremental distances from the outer diameter (OD) surface. These holes simulate artificial defects, allowing operators to verify the system’s ability to detect fine discontinuities under real-world conditions.
