A Digital Coating Thickness Gauge is a precision measuring instrument used to measure the thickness of coatings applied to a substrate without damaging the surface. It is commonly used for paints, varnishes, powder coatings, plating, and other protective layers.

Depending on the measuring principle and model, coating thickness gauges can measure coatings applied to ferrous metals such as steel and iron and non-ferrous metals such as aluminum, copper, and zinc.

Yes. Digital Coating Thickness Gauges generally perform non-destructive testing (NDT), allowing the coating to be measured without damaging the painted or coated surface.

Coating thickness is commonly displayed in micrometers (µm) or mils (mil). Some instruments may also support other measurement units depending on the model.

They are widely used in automotive, construction, manufacturing, metal fabrication, shipbuilding, aerospace, powder coating, painting, electroplating, and corrosion inspection applications.

For reliable and accurate measurements, regular calibration or verification is recommended. Calibration requirements depend on the instrument, application, substrate, and applicable testing standards.

Key advantages include quick measurement, easy-to-read digital display, non-destructive testing, portability, reliable results, and efficient quality control.
