Extech CG304 Specifications

CG304 Coating Thickness

Tester with Bluetooth

Extech’s CG304 offers a non-destructive way of measuring
the thickness of ferrous and non-ferrous substrates with auto
recognition of the material being measured. Unique Bluetooth®
interface feature wirelessly transmits measurement data to your
PC for further analysis and to generate a documented report.

Applications:

- Automotive paint thickness to determine if car has been in an accident before

- Quality inspection and monitoring of the process of anodizing or galvanizing

- Suitable for paint manufacturers, painting inspectors, painters, and anti-corrosion
painting contractors

- Machine tools manufacturers, pipeline industry, and aeronautical industry

Features

• Dual Technology provides automatic recognition of

ferrous and non-ferrous substrates

• Magnetic induction for ferrous substrates

• Eddy current measurement for non-ferrous substrates

• Easy-to use menu system

• Dot matrix LCD display with backlight and contrast

• Memory stores 2500 readings in 50 groups with

50 readings in each group

• Zero-point calibration function

• Bluetooth interface includes software
