This instrument adopts the magnetism measuring thickness methods. It can measure the thickness of the covering layer of non-magnetism (such as aluminum, chrome, copper, enamel, rubber and oil paint) which are covered on the magnetism metal substrates (such as steel, iron, alloy and rigid magnetism steel) It has many characteristics, such as little error of measuring, excellent performance, good stability and easy operation. It is such a necessary measure instrument to control and guarantee the product quality that it is widely applied to manufacturing, metal processing industry, chemical industry and merchandise testing field.
