Principle of Measurement
The coating thickness gauge works either on the magnetic induction principle or on the eddy current principle, depending on the type of probe used. This gauge has an internal F probe and N probe.
·F probe works on magnetic induction principle and should be used for non-magnetic coatings such as aluminum, chrome, copper, zinc, paint and varnish, enamel, rubber,
etc., on an iron or steel substrate; It is also suitable for alloyed and hardened magnetic steel(however, not suitable for austenitic steel).
·N Probe work on the eddy current principle and should be used for insulating coatings e.g. paint, anodizing, ceramics, etc., on all non-ferrous metals such as aluminum,
copper, zinc die casting, brass, etc. and on austenitic stainless steels.
Easy to Carry: Included a storage bag that can be strapped to the user's waist, users would no longer have to worry about carrying problems.
