F represents the ferrous magnetic substrate, F type of coating thickness gauge using electromagnetic induction principle, to measure the the non ferromagnetic coating on metal substrate namely steel and iron, such as: paint, powder, plastic, rubber, synthetic materials, phosphating, chromium, zinc, lead, aluminum, tin, cadmium, ceramic, enamel, oxide layer, etc.

N for Non ferromagnetic substrate, N type of coating thickness gauge using eddy current principle; Measured with eddy current sensor to measure layer of enamel, plastic, rubber, paint, etc. On copper, aluminum, zinc, tin and other substrate. 

FN type of coating thickness gauge using electromagnetic induction principle, as well as the principle of eddy current, is the combined F and N type coating thickness gauge.
