Features： 1、Wide Applications: The coating thickness tester is designed to measure the thickness of coatings and plating on metal surfaces such as paint, porcelain, chrome on steel, and paint and anodized coatings on aluminum, copper. 2、Dual Technology Design: With the use of dual technology, this tester can automatically detect black metal and non ferrous metal substrates, allowing for non destructive measurement of automotive paint thickness. 3、Accurate and Reliable: The measurement range of this tester is 0?1700um (0?59.1mil) with an accuracy of ±(1+3%H). It can accurately measure coatings on various curved surfaces, including a minimum convex curvature of approximately 5mm and a minimum concave curvature radius of 25mm. 4、Efficient and Convenient: The coating paint thickness tester is easy to operate, and it provides fast measurement results, enabling users to quickly obtain coating thickness data, saving time and effort. 5、User Friendly Interface: The coating thickness gauge features a human oriented interface with a backlight LCD display. Users can visually set the parameters before using it. It also allows for easy storage, recall, or deletion of readings.
