Standard MPI Machine

Our standard MPI test bench units establish a benchmark for MPI inspection, finding applications across diverse industries, including automotive, fasteners, hand tools, oil field equipment, railways, and education & training for the detection of surface & subsurface defects. These benches, functioning as two vector machines, create a circular magnetic field by clamping the part between the headstock and tailstock and passing a current through it. The threaded bar method allows the testing of parts with a central bore. Additionally, a longitudinal magnetic field is generated through the use of an encircling coil.


  • Independent current control for Circular and longitudinal magnetization.
  • Separate transformers for Circular and longitudinal magnetization, eliminating the need for noisy changeover switches.
  • Digital, stepless current control.
  • Two large digital readout ampere meters with retention. Pneumatic clamping.
  • Stainless Steel liquid storage tank.
  • Reverse agitation bath system.
  • AC/HWDC changeover for headshot.
  • Continuously movable tailstock with cam lock.
  • V Blocks for job placement.
  • Integrated decaying-AC demagnetization with automatic control.
  • Feedback loop-based current control with current failure indicator.
  • Minimal electronic components for easy serviceability.
