Application of two measuring method :

●Magnetism method (F-probe)
  The probe and the magnetic metal substrate will form a
  closed magnetic circuit when  probe contacting  withthe
  coating themagneticresistanceofclosedmagnetic circuit
  varies  due to the existing of  non-magnetic coating.The
  thickness  of  the coating can be measured through the
  variation of magnetic resistance
                     

              Fig.1-1 principle of magnetism method

  • ●Eddy current method (N-probe)
      The  high frequency    alternating   current generates  an
      electrsomagnetic field in probe coil; eddy current will be
      formed on   metal substrate when  the probe contacting
      withcoating,andtheeddycurrent has aneffectof feedback
      on the coil in probe. The thicknessof the coating can be
      calculated through measuring the effect of feedback.
