Extech CG304: Coating Thickness Tester with Bluetooth

The Extech CG304 is a compact, non-destructive coating thickness tester designed for measuring coatings on both ferrous and non-ferrous metal substrates. It features automatic substrate recognition, allowing fast and accurate measurements using either magnetic induction or eddy current principles depending on the material.

With Bluetooth connectivity, the CG304 allows users to wirelessly transfer up to 2,500 stored readings to a PC for further analysis and reporting. The backlit LCD with contrast adjustment ensures visibility in various lighting conditions. This meter is ideal for quality control, automotive refinishing, manufacturing, and inspection applications.
