EASY OPERATION ON ALL SURFACES – This paint depth meter ensures accurate readings on smooth, rough, curved, and thin surfaces. Ergonomic, lightweight design fits comfortably in your hand for all-day use. SMART MEMORY STORAGE – Stores up to 1500 readings across 100 groups, making it perfect for comparison, data tracking, and industrial quality control. Supports multiple auto shut-off settings to save power. BUILT-IN RECHARGEABLE BATTERY – Powered by a 1000 mAh rechargeable battery, rechargeable via USB cable. Ensures long operating time and convenience for fieldwork or professional use. DUAL UNIT SELECTION – Instantly switch between mils and microns (µm) to match your workflow and measurement needs. Easy-to-read values help minimize interpretation errors. ALL-IN-ONE PAINT THICKNESS TESTER – Works as a coating thickness gauge, automotive paint tester, and metal layer depth checker. Great tool for technicians, car detailers, quality inspectors, and DIY users. The CM-218 Coating Thickness Gauge is a compact, high-precision instrument designed for quick and accurate measurement of coating and plating thickness on virtually any metal surface. Ideal for car buyers, mechanics, detailers, and body shop professionals, this digital paint thickness gauge helps detect repainted, filled, or previously repaired areas on a vehicle, ensuring accurate assessment of paint quality and structural condition before purchase or refinishing. This professional paint thickness tester uses dual measurement technology — magnetic induction for ferrous (Fe) metals and eddy current for non-ferrous (Al) substrates — allowing fully automatic substrate recognition without user input. It delivers exceptional precision with a resolution of 0.1 µm / 0.01 mil and a measuring range of 0–1300 µm (0–51 mil), providing highly reliable readings for automotive, manufacturing, and industrial applications. With an accuracy of ±3%, the CM-218 ensures consistent results even on curved or hard-to-reach surfaces. Unlike many coating thickness meters, the CM-218 does not require frequent calibration, yet it includes a full calibration kit for users who want to verify accuracy at any time. The built-in 1000 mAh lithium-ion battery provides long operating time and charges conveniently via USB, making the device perfect for both professional and mobile use. Its automatic shutdown function helps preserve battery life during extended inspections. Engineered for convenience, this car paint tester features a large, easy-to-read digital LCD display for quick interpretation of data in any lighting condition. The lightweight and ergonomic design allows one-handed operation, enabling accurate measurement even in tight spaces such as door frames, bumpers, or fenders. Thanks to its durable build, the coating thickness meter performs reliably under various environmental conditions.
