Measuring principle and application of coating thickness gauge

The F-type probe is designed according to the principle of magnetic induction and mainly measures the non-magnetic coating on the steel substrate. For example: aluminum, chromium, copper, zinc, paint, rubber, etc., also suitable for alloys and hard steel.

The N-type probe is designed according to the eddy current principle and mainly measures the coating on non-ferromagnetic metals and austenitic stainless steels. For example: aluminum, copper, paint on cast zinc parts, anodized film, ceramics, etc.

The FN type probe is designed by using both the magnetic induction principle and the eddy current principle. One probe can complete the measurement that can be completed by the F-type and N-type probes.
