MPI Field Indicator


A great little calibrated and accurate analogue meter for measuring residual DC Magnetism. It has been used in NDT to determine efficacy of demagnetising processes.

  • Dimensions – 63mm Diameter x 34mm Deep (Gauge Only).
  • Precision Instrument supplied in robust water proof and dust proof case
  • Accurate to within 3% of full scale.
  • +10 to –10 gauss or
  • +20 to – 20 gauss (pictured) or
  • +2 to -2gauss
  • Weight 75 grams
  • Supplied Calibrated and Traceable to National Standards
  • Easy to read and use
  • Field measurements are taken by placing the arrow on the face adjacent to the object in question.
  • Ideal for confirming demagnetisation processes are satisfactory.
  • Extensively used in NDT throughout Government and Military bodies world-wide.
  • Re-calibration service available.
  • Now 20-0-20 model comes with Fluorescent background for ease of viewing in MPI Inspection Booths.
