DC30F Coating Thickness Gauge one of the three models of DC30 series coating thickness gauge, which equips with ferrous probe, adopting magnetic measuring method to measure the thickness of non-magnetic coatings on magnetic metal substrates. Such coatings including paint，plastic film，chromium layer，copper layer, zinc coating, enamel etc.
It is widely used in electronics, power plants, petrochemical industry, aviation, architecture etc.


Using Scopes:
With ferrous probe, it is used to measure non-magnetic coatings on magnetic metal substrates.
►Common non-magnetic coatings:
Painting coating(oil paint, painting, powder spraying), plastic film，rubber layer，erosion resistant coating，synthetic material layer，chromium layer，copper layer, lead layer, aluminum layer, tin layer, cadmium layer, zinc coating, enamel etc..
►Common magnetic metal substrates:
Steel, iron base alloys, cobalt, nickel etc..


Measuring principle of DC30 Series:
►Magnetic Method (Fe): Measuring the thickness of non- magnetic coatings on steel, iron and other ferromagnetic metal substrates, e.g. painting, varieties of anti-corrosion coating, powder spraying, plastic, rubber, synthetic material, phosphate coating, chromium, zinc, Aluminum, tin and cadmium, etc.
►Eddy Current Method (NFe): measuring the thickness of non-conductive coatings on copper, aluminum, stainless steel and other non-ferromagnetic substrates, e.g. painting, varieties of anti-corrosion coating, powder spraying, plastic, rubber, synthetic material, oxide film and phosphate film, etc.
