MT - Magnetic Particle Inspection


CSI utilizes a 600 amp Ardrox Magne-Tech wet horizontal unit suitable for circular or longitudinal magnetic particle inspections of small, medium and large ferrous (magnetic) parts for surface (and near surface) defects. Large quantities of parts can quickly and accurately be processed using this system.
