GAL Gauges

Galvanic gauges, also known as coating thickness gauges, are precision instruments used to measure the thickness of metallic and non-metallic coatings applied to substrates such as steel and other metals.

These devices are essential for evaluating protective layers such as galvanization (zinc), paint, plating, and anodized coatings, ensuring proper application, corrosion resistance, and compliance with industry standards. Most modern gauges operate using non-destructive methods such as magnetic induction or eddy current technology, allowing accurate measurements without damaging the surface. Widely used in manufacturing, construction, automotive, and coatings inspection, galvanic gauges help verify coating quality, detect inconsistencies, and support long-term material performance.
