The F probe is for measuring the thickness of non-magnetic coating layers (aluminum,chrome,copper,ename1,rubber,paint) on magnetic substrate (steel, iron, alloy and magnetic steel)
The N probes is suitable both for the laboratory and for use in harsh field conditions. This meter measures coating film thickness of all non-magnetic coatings such as varnish, paint, enamel, chrome, copper, zircon... on non-ferrous metal base materials.
Also electrically insulating coatings, such as lacquer, paint and anodising coatings on non-ferrous metals are accurately measured.
