The Magnaflux® Tool Steel Ring is intended to be a total system check for your DC output equipment. This test gauge with subsurface discontinuities is an excellent tool that provides a quick way to confirm your DC output machine is working properly.

The Tool Steel Ring is meant to be a quick overall system performance indicator. This ring is to be processed by the continuous method using a 1-inch diameter central conductor. When properly processed, indications of artificial subsurface discontinuities will be produced on the circumferential surface of the ring. The number of indications produced is the function of magnetizing current amperage and the characteristics of the indicating medium.
