Overview
The FR CTG-20 is a high-precision, dual-technology coating thickness gauge. It uses Electromagnetic Induction (for ferrous metals like iron/steel) and Eddy Current (for non-ferrous metals like aluminium/copper) to measure the thickness of non-conductive coatings such as paint, enamel, or plastic on metal surfaces. Its fast response and high accuracy make it ideal for automotive inspection and industrial applications.
Key Features
- Automatic Substrate Detection: Identifies Fe (iron/steel) and NFe (aluminium/copper) automatically.
- Three Measurement Modes: Single, Continuous, and Difference measurement modes.
- High Resolution: Measures in μm, mm, and mil with precise accuracy for thin coatings.
- Calibration Support: Zero and multi-point calibration with included foils.
- Backlit LCD: Clear display with 180° rotation for easy viewing.
