PHASCOPE PMP10 DUPLEX镀锌层测厚仪
The PHASCOPE® PMP10 DUPLEX has been developed for the precise measurement of the individual layer thicknesses of duplex coatings (lacquer/zinc coating system on steel or iron).
Due to the novel phase-sensitive eddy current method, it is capable of measuring very precisely zinc coatings with thicknesses between 0 µm and about 100 µm.
In this manner, it is far superior to conventional eddy current coating thickness measuring instruments that are to reduce the influence of a fluctuating zinc coating on the measurement of the lacquer thickness by a special “phase adjustment” or an increased measurement frequency.
In particular thin zinc coatings in a range of 0 – 10 µm on auto bodies can be measured very reproducibly.
Typical applications are in the quality assurance of
Auto body painting
Shopping carts and similar
Brake line tubes and many others
Zinc alloy coatings such as ZnNi or ZnFe cannot be measured due to their low electr. conductivity.
The same applies to hot-dip galvanized coatings due to diffusion coatings that are typically present and have different electr. conductivities compared to pure zinc coatings.
