How to choose a coating thickness gauge and its principle
With the continuous development of the metal surface pretreatment industry, especially in the global scope, the green environmental protection is highly valued. Nowadays, the coating process of the automobile and auto parts industry has higher technical requirements and higher requirements for process testing. It is also playing an active role in energy saving, emission reduction and environmental protection. The Portable Coating Thickness Gauge is an ultra-compact measuring instrument that can quickly, without damage and accurately measure the thickness of non-magnetic coatings on magnetic metal substrates.
Ferrous/non-ferrous coating thickness gauges use magnetic sensors to measure non-ferromagnetic coatings and coatings on ferromagnetic metal substrates such as steel and iron, such as paints, powders, plastics, rubber, synthetic materials, phosphating layers , chromium, zinc, lead, aluminum, tin, cadmium, porcelain, enamel, oxide layer, etc. Use eddy current sensors to measure enamel, rubber, paint, plastic layers, etc. on substrates such as copper, aluminum, zinc, and tin. Widely used in manufacturing, metal processing industry, chemical industry, commodity inspection and other testing fields.
