Specifications:This product is mainly used to measure the thickness of non- coating on metal surface, as well as the thickness of non-ferromagnetic coating on ferromagnetic metal (such as iron, nickel, cobalt, etc.), such as paint thickness on automobile surface, coating thickness of metal parts and so on. This product also has built-in magnetic induction and vortex double principle probe, can automatically identify the measured metal substrate, only need to be placed on the measured surface, can automatically calculate the thickness of the coating. 1. The thickness gauge is used to measure the thickness of the plated and coated sheet on metal, e.g. paint/enamel/ chrome on steel, paint and coating on aluminum/copper.2. The measuring range is 0-2000UM. 3. The gauge takes the precision integrated probe, and uses principles of electro-magnetic induction and current effect, which automatically detects the attribute of substrates.4. The Gauge is designed for non-destructively measuring the thickness of coating and painting. 5. It is for material surface treatment and widely used in manufacturing industry, metal-processing industry, industry, commodity inspection area, and also to work steadily in the laboratory, workshop and outdoor.
