The PHASCOPE® PMP10 DUPLEX combines three different methods for measuring automotive duplex coatings. The magnetic induction method according to DIN EN ISO 2178 measures the overall thickness of paint/zinc coatings on iron. The amplitude-sensitive eddy current method, DIN EN ISO 2360, measures a single paint layer on the aluminum. The phase-sensitive eddy current method ISO 21968 measures just the zinc coatings on iron, ignoring any overlying paint layers.
