Measuring Principle

The instrument adopts eddy current thickness measurement method (NFe Probe):

Measure non-conductive coating on non-magnetic metals substrate (such as paint coatings on enamel, plastic, rubber, copper, aluminum, zinc, tin substrates).
The electromagnetic field is generated by using high-frequency alternating current in the coil. When the probe contacts the cover, an eddy current in the metal substrate is generated and fed back to the coil in the probe, which is obtained by measuring the feedback effect of the coating thickness.

Measuring Conditions

a) The characteristics of substrate

Standard methods for magnetic substrate of magnetic properties and surface roughness should be similar to the magnetic properties and surface roughness of specimens substrate.

For eddy current method, the standard substrate of electrical properties should be similar to the electrical properties of specimens substrate.

b) The thickness of substrate

Check whether the thickness of the substrate is lower than the minimum thickness, if not, can use one of method in 3.3 to calibrate.

c) Edge effect

Should not be in the specimen shape changing places, such as edges, holes, and the place such as Angle measurement.

d) The curvature

Should not be in curved surface measurement of the specimens.

e) Measurement and measured times

Usually as a result of the instrument measurement result is not the same each time, so we must in every area from several measurement results.Coating thickness and surface rough degree of local differences, require at any repeated measurements in a specific area.

f) Surface cleanliness

Before measurement, should remove any attached on the surface of a material, such as dust, grease and corrosion products, but do not remove any covering material.
