It meets the standards of both ISO2178 and ISO2360 as well as DIN, ASTM and BS.Suitable for the laboratory and for use in harsh field conditions.
The F probes measure the thickness of nonmagnetic materials (e.g. paint, plastic,porcelain enamel, copper, zinc, aluminium,chrome etc.) on magnetic materials (e.g.iron, nickle etc.) . often used to measure the thickness of galvanizing layer, lacquer layer, porcelain enamel layer, phosphide layer, copper tile, aluminium tile, some alloy tile, paper etc.
The N probes measure the thickness of non-magnetic coatings on non-magnetic metals. It is used on anodizing, varnish,paint, enamel, plastic coatings, powder,etc. applied to aluminum, brass, nonmagnetic stainless steel, etc.
