It can measure the thickness of non-magnetic coating layers covered on magnetic substrate. Such as: non-magnetic (aluminum,chrome,copper, enamel, rubber, paint) covered on magnetic substrate (steel, alloy and magnetic stainless steel).It also canmeasure the thickness of non-conductive coatings layers covered on conductive substrate. Such as: (enamel, rubber paint, vanish,plastic anodic-oxide layer) covered on conductive substrate (aluminum, brass, zinc and nonmagnetic stainless steel).
