Description: Thickness gauge is used to measure the thickness of electroplated and coated plates on metal. designed for non-destructively measuring the thickness of coating and painting. Uses principles of electro-magnetic induction and the eddy current effect, which automatically detects the attribute of substrates. The measuring range is 0-2000UM.Measurement Resolution only 0.001 mils. LCD display, you can clearly view the results and statistical measurement data. Widely used in manufacturing, metal processing , chemical , painting workshop, automobile and other fields.
