TT***0F/N Coating Thickness Gauge Introduction The instrument adopts the magnetic and eddy current principle to measure in a non-destructive way .The instrument is a portable thickness-measuring meter, it can measure the thickness of coating and plating rapidly, non-destructively and precisely. It can be used both in lab and the work site. This gauge can be widely used in the inspection fields, ***** manufacturing, metal processing, chemical industry and commodity inspection, etc. It is a gauge essential for the material protection. The meter meets the following standards: GB/T ***6─***3 Measuring Thickness of the Nonmagnetic Coating on a Magnetic Metallic Substrate, Magnetic GB/T ***7─***3 Measuring Thickness of all electrically insulating coating on nonferrous metals, Eddy current Way Measuring Principle The instrument adopts the magnetic and eddy current principle to measure in a non-destructive way a) Magnetic way (TT***0F, type F probe) measure the thickness of non-magnetic coatings on magnetic metallic base (***** zinc, aluminum, Cr. Copper, rubber, paint, coating on the base of steel, iron, alloy and hard magnetic steel etc.) b) eddy current way (TT***0N, type N probe ) measure all electrically insulating coating layers, such as lacquer, Varnish, paint, anodizing coating on nonferrous metals, also on austenitic VA steel materials.
