Introduction
The Coating Thickness Gauge is a precision instrument designed for non-destructive measurement of coating thickness on ferromagnetic substrates such as steel and iron. It is ideal for automotive, industrial manufacturing, and quality control applications. The device delivers high-accuracy results on flat or curved surfaces, including paint, powder coatings, ceramic, chrome, copper, zinc, and anodized layers. Its compact, ergonomic design makes it suitable for both laboratory and field inspections.
