Extech CG204 Coating Thickness Tester is a portable meter designed for non-invasive coating thickness measurements. The CG204 uses two measurement methods: magnetic induction (for ferrous metal substrates) and eddy current (for non-ferrous metal substrates). The meter is easily configured using the intuitive push-button programming menu. Five film reference samples and two metal substrates are provided. The meter is also equipped with a USB PC interface port and PC software. |
