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.

The 224 AUTO Coating Thickness Gauge (2025 Update) by VVV-Group is a next-generation digital paint thickness meter engineered for fast, precise, and non-destructive measurement of coatings and paints on metal surfaces. Designed for automotive professionals and enthusiasts alike, it delivers laboratory-level accuracy in a compact, durable form—ideal for car buyers, body shops, appraisers, and detailing specialists. The 224 AUTO supports both ferrous (Fe) and non-ferrous (Al, Cu) substrates, automatically detecting material type and adjusting the measuring mode. Its unique Fe+Zn function identifies the presence of zinc coating (galvanization), allowing users to detect replaced or non-original body panels—an essential advantage for used-car inspections and authenticity verification. With a measurement range of 0–1500 µm (0–59.1 mils), resolution of 0.1 µm / 0.01 mil, and accuracy ±3%, the 224 AUTO ensures consistent and trustworthy readings on every test. Zero-point and multi-point calibration guarantee long-term stability, while the factory reset option instantly restores default settings for quick setup in the field. Built for real-world automotive environments, this paint thickness tester features a shock-absorbing rubber case for impact protection and an ergonomic grip with an included wrist strap for secure handling. The large backlit LCD display and oversized buttons provide effortless operation even with gloves, making it perfect for workshop or outdoor use. The 224 AUTO coating thickness gauge performs reliably across a wide temperature range (–20 °C to +40 °C / –4 °F to 104 °F) and humidity up to 90%, ensuring dependable performance in any climate. Compatible with steel, iron, aluminum, and copper, it is not suitable for plastic or carbon-fiber panels. Applications Automotive inspection: Detect repainted or filled panels and verify original paint thickness. Car detailing: Measure coating layers before polishing or ceramic coating. Body shops & QA: Check paint uniformity and coating adhesion after refinishing. Vehicle appraisal: Assess authenticity and repair history with precision. Technical Highlights Measuring principles: Magnetic induction (Fe) & Eddy current (NFe) Range: 0–1500 µm (0–59.1 mil) Resolution: 0.1 µm / 0.01 mil Accuracy: ±3% Functions: Fe+Zn mode, Zero & multi-point calibration, factory reset Display: Large backlit LCD Power: AAA batteries (included) Temperature range: –20 °C to +40 °C (–4 °F to 104 °F) Humidity tolerance: ≤ 90% RH Units: µm / mm / mil Package Includes 224 AUTO Coating Thickness Gauge Calibration foils (50–1000 µm) Fe and Al substrate plates Wrist strap & protective cloth bag 2 × AAA batteries English user manual Compact, robust, and easy to operate, the 224 AUTO combines precision, durability, and intelligent design—making it the ultimate paint thickness gauge for automotive diagnostics, detailing, and inspection professionals.
