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 instrument can be widely used in the inspection fields, e.g. 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 4956─2003 Measuring Thickness of the Nonmagnetic Coating on a Magnetic Metallic Substrate, Magnetic GB/T 4957─2003 Measuring Thickness of all electrically insulating coating on nonferrous metals, Eddy current Way.
