  • This can measure products of any shape.
  • The measurement process is automatic, and the operation is simple.
    Anyone can take measurements in a short time with excellent reproducibility.
  • Operation consists only of putting a target product, and setting the range.
    Even an alarm is available to alert you of the proper range setting.
  • A lock-in amplifier is used for magnetic detection parts.
    Supersensitivity and low noise make it possible to measure the magnetic thin film for spattering.


  1. Inspection of soft magnetic material properties
    Plate, bars, thin film, powder
  2. Quality control for soft magnetic parts
    Solenoid valves, relays, transformers, cores for EFI, etc., card readers, audio, cores for VTR heads, etc.
  3. Understanding the impact on the manufacturing process for magnetic properties
    Heat treatment conditions, furnace dispersion, welding, pressing, caulking, cutting off, grinding, polishing, plating, etc.
