Unveiling The Extech Cg204: Exploring Specifications, Manuals, Pros And Cons, And Common Problems

Extech CG204 Information

The Extech CG204 is a portable, non-destructive coating thickness tester that uses dual technology to measure the thickness of coatings on ferrous and non-ferrous metal substrates. The meter features automatic recognition of the substrate material, single and continuous measurement modes, 400-reading memory storage, and user-programmable high/low alarms. It also comes with a USB PC interface port and PC software for data transfer and analysis.

Introduction

The Extech CG204 is a versatile and easy-to-use coating thickness tester that is ideal for a variety of applications, including:

Inspection of painted surfaces
