Coating Thickness Gauges (also known as paint meters) are precision instruments used to measure the dry film thickness (DFT) of non-magnetic coatings—such as paint, enamel, plastic, or chrome—applied to metal substrates. This category features both Ferrous (F) gauges for steel and iron and Non-Ferrous (N) gauges for aluminum and copper, as well as Dual-Function units that automatically detect the base material. Essential for quality control in automotive, marine, and industrial coating sectors, these gauges ensure that protective layers are thick enough to prevent corrosion but thin enough to avoid cracking or wastage. Our selection includes portable digital units with built-in statistics and data logging, providing the accuracy needed to meet strict ISO and SSPC standards.
