A coating thickness gauge, also known as a paint meter, is a tool used to accurately mesaure dry film thickness. In the coatings industry, dry film thubsickness is arguably the most critical measurement due to its significant impact on the coating process, quality and cost. Dry film thickness measurements are an essantial tool for evaluating a coating's expected life, the product's appearance and performance, and ensuring complience with a range of international standards. The dry coating measurement process utilises a digital thickness gaugei enabling precise and non-destructive thickness measurement on various surfaces, including magnetic steel and non-magnetic metals such as stainless steel and aluminium. Digital coating thickness gauges are the ideal solution for measuring coating thickness on metallic substrates. Electromagnetic induction is used for non-magnetic coatings on ferrous substrates, such as steel, whilst the eddy current principle is used for non-conductive coatings on non-ferrous metal substrates.
