Coating or paint Thickness Gauges are used to measure paint thickness on material surfaces, control manufacturing quality and inspect automotive or used car paint. Various paint Thickness Gauges, conductivity meters or automotive paint Thickness Gauges can be used for non-destructive measurement of non-magnetic paints, coatings, insulation and dry film thickness (DFT) on ferrous or non-ferrous metal substrates (such as copper) . steel, iron or aluminium.
Digital paint Thickness Gauges are important coating and quality inspection tools when anodizing, galvanizing and galvanizing metal surfaces. Coating Thickness Gauges can also be used to measure paint thickness and uniformity on used cars, uncover repaint spots, identify hidden damage and expose undisclosed accidents. This feature is very useful in determining the actual value of a used car. Powder coating Thickness Gauges are used to measure the thickness of powder coatings, which are electromagnetic or eddy current Thickness Gauges on powder-coated metal substrates.
