Black Magnetic Ink
Highly sensitive oil-based black suspension for instant defect indication.
MR 76S is a high-grade black magnetic ink (oil-based) containing finely divided ferromagnetic particles. When applied to a magnetized surface with a white contrast background (MR 72), it quickly migrates to leakage fields caused by surface and near-surface defects, providing sharp and unambiguous indications.
