A pocket-sized digital coating thickness gauge that uses electromagnetic induction and eddy-current sensing to measure paint, powder-coat, and other non-metallic coatings on metal, with a range up to about 1.8mm (71 mil) and accuracy around +/-0.03mm. It supports zero, one-point, and two-point calibration, switches between metric and imperial units, and offers single, continuous, and difference measurement modes with auto power-off.
