Uses both magnetic and eddy current measurement methods to non-destructively detect the thickness of non-magnetic coatings on magnetic metal substrates (such as aluminum, chromium, copper, zinc, tin, rubber, and paint on steel, iron alloys, and hard magnetic steel), as well as the thickness of non-conductive insulating coatings on non-magnetic metal substrates (such as rubber, plastic, paint, and oxide films on aluminum, copper, zinc, and tin).
Application
The coating thickness gauge is widely used in electroplating, corrosion protection, aerospace, aviation, chemical industry, automotive, shipbuilding, light industry, commercial inspection, and other fields. It is suitable for both laboratory and on-site engineering applications. By configuring different probes, it can be adapted to various scenarios, making it an essential tool in the non-destructive testing industry.
