Paint Thickness Gauge CM-224 Auto – Digital Coating Thickness Meter for Cars and Automotive Inspection, Fe / Al / Fe+Zn Detection, 0.1 μm Resolution, Factory Calibrated, Large Backlit LCD

HIGH ACCURACY — READY TO USE FOR CAR INSPECTION: Professional paint thickness gauge with factory-calibrated accuracy for automotive inspection. Delivers precise measurements immediately after battery installation — no calibration required for car body checks. Resolution 0.1 μm (0.01 mils), range 0–1500 μm (0–59.1 mils). EASY & FAST OPERATION — NO SETUP REQUIRED: Automatic substrate detection and pre-set factory calibration allow instant use out of the box. Large backlit LCD and intuitive controls make this coating thickness meter ideal for both professionals and first-time users. AUTOMATIC Fe / NFe / Fe+Zn SUBSTRATE DETECTION: Automatically recognizes steel (Fe), aluminum (NFe), and galvanized steel (Fe+Zn). Fe+Zn detection helps identify replaced or non-original car body panels during used car inspection. DESIGNED SPECIFICALLY FOR AUTOMOTIVE INSPECTION: Accurately evaluates paint thickness, repainting, and filler presence on metal car panels. Ideal for used car buyers, vehicle appraisers, body shops, and detailing professionals. DUAL MEASURING TECHNOLOGY FOR METAL SURFACES: Uses magnetic induction for ferrous metals and eddy current technology for non-ferrous metals, ensuring stable and repeatable measurements on steel, aluminum, and copper substrates. SINGLE & CONTINUOUS MEASUREMENT MODES: Supports single-point (SNG) mode for precise spot checks and continuous (CON) mode for rapid scanning of large vehicle panels. OPTIONAL ADVANCED CALIBRATION & FACTORY RESET: Supports zero calibration and multi-point calibration for special materials or professional applications. Instant factory reset restores default settings at any time — useful after incorrect calibration or extended use. METAL SURFACES ONLY — CLEAR & HONEST LIMITATION: Designed exclusively for metal substrates (steel, iron, aluminum, copper). Not suitable for plastic, carbon fiber, or composite parts, preventing incorrect expectations and misuse.
