The gauge is used to measure the thickness of metal plating and coatings such as paint, enamel, and chrome on steel, as well as paint and anodic oxide coatings on aluminum and copper. It automatically detects the substrate material and enables non-destructive measurement of coating and paint thickness. This device is widely used in manufacturing, metal processing, chemical industry, and commercial inspection. It operates reliably in laboratory, workshop, and outdoor environments. Features: Easy Operation: Built-in magnetic induction and eddy current dual principle probe automatically identifies the metal substrate. Simply place it on the surface to measure coating thickness. Digital LCD Display: Backlit digital display supports statistical data viewing, including average, minimum, maximum, and count. Stores up to 50 data points; when full, the newest reading replaces the oldest, with automatic update of statistical values. Three Probe Modes: Offers automatic (AUTO), magnetic induction (F), and eddy current (NFE) modes for flexible use based on application needs. Unit Switching Function: Allows switching between micron (µm), millimeter (mm), and mil units. Zero Calibration: Recommended for improved accuracy to ensure reliable results. Multifunctional Design: Includes battery level indicator, automatic power-off after 3 minutes of inactivity, and backlight on/off control. Statistical Display: Provides clear view of average, minimum, maximum, and number of measurements. Supports up to 50 data points with automatic overwrite and update. Standard Aluminum Film: Includes calibration base sheet and six calibration films with thicknesses of 0.05mm, 0.10mm, 0.25mm, 0.50mm, 1.00mm, and 2.00mm. Measurement Object: Designed for non-destructive measurement of non-conductive coatings on metal surfaces and non-ferromagnetic coatings on ferromagnetic metals such as iron, nickel, and cobalt. Suitable for applications like automotive paint and metal part coatings. Wide Applications: Commonly used in manufacturing, metal processing, chemical industry, and quality inspection. Stable performance in laboratory, workshop, and field environments.
