Elektrophysik MikroTest Magnetic Coating Thickness Measuring Gauge

NDT Equipment Sales


The Elektrophysik MikroTest® has been the most widely used coating thickness gauge in the world over the last 40 years. International patents and our production “know-how” ensure that the gauge has the highest technical standards of all analogue magnetic coating thickness gauges. All instruments conform to national and international standards: DIN EN ISO 2178, DIN 50982, ASTM B 499, E 376, D 1186, G 12, B 530, BS 5411, ISO 2361.


Eleven models for every application are available in the MikroTest range.

The balanced measuring system ensures accurate readings at any angle.

  • Horizontal, vertical, overhead.
  • The gauge allows measurements on curved surfaces.
  • Precise measurements in tubes and on round parts due to the automatic operation.

Measuring Principle:

The measurement of the coating thickness is based on magnetic attraction.  The attractive force is related to the distance between a permanent magnet and a steel substrate.  This distance represents the thickness of the coating to be measured.  The magnet is lifted from the surface by means of a spring connected to the magnet arm.  The force needed to lift the magnet is directly related to the angle of rotation of the torsion spring.  This measuring principle is also especially suited for electroplated nickel on copper, aluminium and other non-ferrous metals.
