With different probe: 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 can measure 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).
Main feature:
*Various probes optional, probe auto matching.
*Durable ruby probe, more wear and precise.
*Full metal shell design, sturdy, portable, high reliability.
*Alarm function when overrun the settable limiting range.
*Five statistics values [MEAN, MAX, MIN, NO., S.DEV] higher measurement accuracy.
*Large storage, easy to delete single or multiple saved values..
*PC software optional, convenient the data transmission, analysis, printing etc.
