Coating Thickness Gauge (For Nickle, NiFe-50) Elektrophysik

MikroTest Magnetic coating thickness measurement standards for checking the accuracy

Application

The 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 50 982, ASTM B 499, E 376, D 1186, G 12, B 530, BS 5411, ISO 2361

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.
