Fnirsi Ctg-20 Car Paint Thickness Gauge 0-1400um Coating

Meet the Fnirsi CTG-20 Car Paint Thickness Gauge — a compact, high-precision device designed to measure coating thickness on metal surfaces with ease. Using advanced electromagnetic induction and eddy current technology, this gauge delivers non-destructive, fast, and accurate readings of paints and electroplated coatings on both ferrous and non-ferrous materials. Its automatic substrate detection and built‑in backlight make it ideal for automotive refinish shops, manufacturing QA, and quality control laboratories. Calibrate quickly with zero-point or multi-point calibration to ensure consistent accuracy across substrates. With a robust 600mAh battery, the CTG-20 provides reliable performance when you need it most. Providing quality and trusted service since 2002 at intercyprus.com.

Benefits & Tips

• Non-destructive coating testing for ferrous and non-ferrous metals—perfect for automotive, manufacturing, and field inspections.
• Fast, accurate readings (0–1400 μm) with ±3% + 2 μm accuracy and 0.1 μm resolution, plus automatic substrate detection to simplify setup.
• Flexible calibration—zero-point and multi-point calibration options ensure reliable results across different coatings and substrates; backlit display aids readability in dim environments.
