In built probe(s).
1.FEATURES
* It meets the standards of both ISO2178 and ISO 2361 as well as DIN, ASTM and BS. It can be used both in the laboratory and in harsh field conditions.
* The F probes measure the thickness of non-magnetic materials (e.g. paint, plastic, porcelain enamel, copper, zinc, aluminum , chrome etc.) on magnetic materials (e.g. iron, nickel etc.) . often
used to measure the thickness of galvanizing layer, lacquer layer, porcelain enamel layer, phosphide layer, copper tile, aluminum 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, non-magnetic stainless steel, etc.
* Automatic substrate recognition.
* Manual or automatic shut down.
* Two measurement mode: Single and Continuous
* Wide measuring range and high resolution.
* Metric/Imperial conversion.
* Digital backlit display gives exact reading with no guessing or errors.
