Magnetic non-destructive coating thickness gauge for all non-magnetic coatings on steel and electro nickel on steel.

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
