Application areas of coating thickness gauges
The coating thickness gauge can non-destructively measure the thickness of non-magnetic coatings (such as aluminum, chromium, copper, enamel, rubber, paint, etc.) and non-magnetic coatings on magnetic metal substrates (such as steel, iron, alloys and hard magnetic steel, etc.) The thickness of the non-conductive coating (such as enamel, rubber, paint, plastic, etc.) on the metal substrate (such as copper, aluminum, zinc, tin, etc.).
1. Electroplating and spraying: Electroplating or spraying on metal surfaces can effectively protect the service life of raw materials and play an aesthetic role. Therefore, a large number of electroplating factories and spraying industries have emerged. At the same time, coating thickness gauges have also been developed for the development of the coating industry. .
2. Metal hardware industry: Hardware workpieces are prone to oxidation and corrosion when exposed to the air for a long time. Therefore, one or more protective coating layers are required on the surface, and buyers and sellers need to test the products.
3. Machinery manufacturing industry: chrome plating of molds, hard chrome plating of rollers, chrome plating of automobile surfaces, and galvanizing of accessories all require coating thickness testing to provide more effective protection for workpieces.
4. Steel structure: Enterprises with our products can also be classified as an industry separately. Coating thickness gauges do have a lot of applications in this industry, including iron towers, bridges, supports, highway barriers, ship plates and many other related manufacturers. They are also in high demand.
The difference between magnetic (iron-based) and eddy current (non-iron-based) coating thickness gauges
Coating thickness gauge magnetic (iron-based) measures the thickness of non-magnetic coatings (such as aluminum, chromium, copper, enamel, rubber, paint, etc.) on magnetic metal substrates (such as steel, iron, alloys and hard magnetic steel, etc.)
Coating thickness gauge eddy current (non-ferrous based) measures the thickness of non-conductive coatings (such as enamel, rubber, paint, plastic, etc.) on non-magnetic metal substrates (such as copper, aluminum, zinc, tin, etc.).
Magnetic (Iron-based) Type F:
Measuring the thickness of non-magnetic coatings on steel, iron and other ferromagnetic metal substrates, such as: paint, powder, various anti-corrosion coatings, plastics, rubber, synthetic materials, phosphate layers, chromium, zinc, lead, tin, cadmium wait;
Eddy current (non-ferrous based) N type:
Measure the thickness of all non-conductive layers on non-ferromagnetic substrates such as copper, aluminum, stainless steel, etc., such as: paint, powder, various anti-corrosion coatings, plastics, rubber, synthetic materials, phosphate layers, oxide layers, etc.;
FNF type:
It is a combination of the above F type and N type, which is what we often call a dual-purpose thickness gauge.
