DC30N Coating Thickness Gauge one of the three models of DC30 series coating thickness gauge, which equips with non-ferrous probe, adopting eddy current measuring method to measure the thickness of non-conductive coatings on copper, aluminum, stainless steel and other non-ferromagnetic substrates, e.g. painting, varieties of erosion resistant coating, powder spraying, plastic, rubber, synthetic material, oxide film and phosphate film, etc.
It is widely used in electronics, power plants, petrochemical industry, aviation, architecture etc.

Using Scopes:
With non-ferrous probe, it is used to measure non-conductive coatings on non-magnetic substrates.
►Common non-conductive 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 non-magnetic metal substrates:
Copper，Stainless Steel Aluminum，Gold，Silver and almost all the metals except iron, cobalt and nickel.

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.
