The Extech CG206 Coating Thickness Tester is a portable meter that allows for quick, one-handed operations, and nondestructive measurements of the coating thickness on various surfaces. The meter uses two measurement methods: magnetic induction (for ferrous metal substrates) and eddy current (for non-ferrous metal substrates). The CG206 meter can connect to a PC via USB and transmit recorded data for further analysis and for generating report documentation. The product additionally features dual technology that provides automatic recognition of the ferrous and non-ferrous substrate materials under test.
