Feature: 1. [Versatile Measurement] The paint coating thickness gauge is ideal for measuring the thickness of coatings on metals, such as paint, enamel, chrome, and anodized coatings on steel, aluminum, copper, and can automatically detect the substrate material. 2. [Data Recording and Analysis] This coating thickness tester can record average, maximum, minimum, and difference values simultaneously and support statistical analysis of up to 50 data points. Auto power off function helps conserve battery life by automatically shutting off after 3 minutes of inactivity. 3. [Wide Application] Ideal for measuring non conductive coatings on metal surfaces and non magnetic coatings on ferromagnetic metals (such as iron, ni, cobalt), the paint thickness measuring tool is great for determining paint thickness on car surfaces, metal parts, and more. 4. [3 Measurement Units] With three measurement units (um, mm, mils), this digital coating thickness gauge allows for quick and accurate measurement of coating thickness on almost all metal surfaces. 5. [Non Destructive Testing Tool] This instrument is essential for non destructively measuring the thickness of coatings and paints, widely used in industries such as manufacturing, metal processing, can reliably operate in laboratories, workshops, outdoors.
