Measuring Principle
a) Magnetic method (F Probe)
Measuring Non-magnetic coatings on magnetic substrates (such as aluminum,chromium, copper, rubber coatings on steel, iron, alloy and hard magnetic steel substrates).
When the probe contact with cover, measuring probe and magnetic metal matrix form a closed magnetic circuit, as a result of the existence of a nonmagnetic layer, make the magnetic circuit magnetic resistance change, can be derived by measuring the change the thickness of coating
b) Eddy current method (N Probe)
Measuring Non-conductive coatings on Non-magnetic basis metals (such as enamel, plastic, rubber, paint coatings on copper, aluminum, zinc, tin substrates).
By using high frequency alternating current in the coil produces an electromagnetic field,when the probe contact with cover,Metal substrate eddy current is produced,and feedback to a coil in a probe,Derived by measuring the size of the feedback effect of the coating thickness.
Measuring method(Singe & Continuous)
1, Singe──when Probe touch the surface, 1 test will display 1 measuring result, with a hun sound.
2, Continuous──Probe sliding on surface, the screen will blink changing measurements, without notice sound (Tip: This method would abrade the probe)
3, Conversion
