The MikroTest is a highly durable coating thickness measurement gauge to enable the measurement of non-magnetic coatings on steel using magnetic adhesive force. A metal casing makes it highly robust and resistant against harsh environmental conditions.

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.
Manual Mikrotest - Turn the scale wheel to the forward stop and then slowly turn the wheel backwards by hand until the magnet releases from the object to be measured.
Automatic Mikrotest - Before measuring the scale wheel is turned as far as it will go and once started the built-in locking mechanism automatically carries out the process of measurement.
