Digital Coating Thickness Tester / DFT Meter


Galaxy CTG-800 is a feature loaded coating thickness tester. This device works on the principle of eddy-current. It can measure coating on both ferrous & non-ferrous bases. It can be calibrated up to 5 points and calibration standards are provided along.

SKU: CTG-800 Category:


• Large display & built-in Black Light for easy reading
• V-Groove for easy reading
•Single & Continuous reading mode
•Auto power-off in 5 minutes with no-operation
•Automatic Fe/Nf recognition
•Anti-skid rubber grip

The thickness gauge is used to measure the thickness of coating on metal, e.g. paint/enamel/chrome on steel, paint and anodizing coating on aluminum/copper.
