HIGH ACCURACY COATING THICKNESS MEASUREMENT – Digital paint thickness gauge for metal surfaces with 0.1 μm (0.01 mils) resolution and ±(3%+2 μm) accuracy, helping detect repainting, repairs, and uneven coating thickness during used car inspection, detailing work, and professional quality control. Suitable for checking doors, hood, roof, fenders, and other painted metal panels where accurate coating evaluation is required. EASY & FAST OPERATION — FACTORY CALIBRATED – Factory calibrated and ready to use right after installing batteries. Large backlit LCD with clear readings and simple buttons make this coating thickness meter easy for professionals and first-time users. Ideal for pre-purchase vehicle checks, car dealership inspections, trade-in evaluation, and mobile appraisers who need quick and convenient measurements without complicated setup. AUTOMATIC Fe / NFe SUBSTRATE DETECTION – Automatically detects Fe (steel/iron) and NFe (aluminum/copper) and selects the correct measuring method. Ideal for modern vehicles with mixed body materials and accurate results without manual switching. This helps users inspect steel doors, aluminum hoods, and other metal body parts with the correct measurement principle applied automatically. WIDE MEASURING RANGE FOR AUTOMOTIVE & INDUSTRIAL USE – Measuring range 0–1500 μm (0–59.1 mils) covers factory paint, repainting layers, and thicker coatings. Suitable for car body panels and industrial coated metal parts. Whether checking original automotive paint thickness or verifying thicker coating applications on metal components, the gauge provides a practical working range for many inspection scenarios. DUAL TECHNOLOGY: MAGNETIC INDUCTION + EDDY CURRENT – Uses magnetic induction for ferrous metals and eddy current technology for non-ferrous metals, providing stable, repeatable measurements across steel, iron, aluminum, and copper substrates. This dual-technology design allows one device to cover common automotive body metals without requiring separate meters or manual probe replacement. SINGLE & CONTINUOUS MODES (SNG / CON) – Supports single-point mode for spot checks and continuous mode for fast scanning of large panels such as doors, hood, roof, and quarter panels. Helps speed up inspections while confirming consistent coating thickness and identifying abnormal areas that may indicate repainting, filler, or previous repair work. OPTIONAL CALIBRATION + INSTANT RESET – Supports zero calibration and multi-point calibration using included metal plates and foils. If settings were changed, press and hold reset to restore default calibration instantly for reliable measurements. This allows both quick everyday use and additional verification when more controlled measurement conditions are needed. METAL SURFACES ONLY — CLEAR LIMITATION – Designed only for metal substrates (Fe and NFe). Not suitable for plastic bumpers, carbon fiber, fiberglass, or composites. This prevents incorrect use and helps users understand the proper application of the device before inspection, reducing false expectations and improving measurement reliability on supported surfaces.
