The Elcometer range of digital coating thickness gauges has been specifically designed to provide highly accurate, reliable and repeatable coating thickness measurements on almost any substrate, whether ferrous or non-ferrous. Dry Film Thickness can be measured on either magnetic steel surfaces or non-magnetic metal surfaces such as stainless steel or aluminium using a digital coating thickness gauge. The principle of electromagnetic induction is used for non-magnetic coatings on magnetic substrates such as steel. The eddy current principle is used for non-conductive coatings on non-ferrous metals substrates. Elcometer offer a range of digital coating thickness gauges from the new Elcometer 456 - available with either integral or separate probes, the Elcometer 415 Paint and Powder Thickness Gauge, to the Elcometer 311 Automotive Refinishing Gauge.
