The GM200A Coating Thickness Gauge is a portable, digital tool used to measure the thickness of non-metallic coatings—such as paint, film, or powder—on metal surfaces. It is primarily used in the automotive industry to identify if a vehicle has been repainted, as well as in manufacturing and quality inspection.
Key Features
Non-Destructive Measurement: Quickly measures thickness without damaging the surface.
Dual Operating Modes:
Car Mode: Uses built-in factory data for quick checks on iron, aluminum, and zinc without needing manual calibration.
User Mode: Requires manual calibration with included films for more precise, specialized measurements.
Three Measurement Modes: Supports single measurement (one data point), continuous measurement (real-time updating), and differential measurement (difference between current and previous reading).
LCD Digital Display: Features a clear screen for reading results in either metric (mm) or imperial (mil) units.
Calibration Support: Includes three calibration methods: zero calibration, two-point calibration, and basic calibration to maintain accuracy.
