Knowing the thickness of dry film is paramount in the coating application process.
It gives key data with regards to the longevity of the substrate, the item’s readiness for service, its appearance and guarantees consistence with a large number of International Standards. Quality parameters such as those depicted in ISO 9000, ISO 17025 and Guide 25, necessitate that the instruments be appropriately controlled, logged and calibrated. Progressively, clients are determining that the readings taken by instruments, conform to National Standards. In 1947, prior to appearance of consumer electronics, Elcometer introduced one of the world’s first non-aggressive coating thickness gauges, the Elcometer 101.
The Elcometer line of digital thickness gauges has been carefully crafted to give scientifically exact, dependable and repeatable covering thickness estimations on practically any surface, be it ferrous or non-ferrous. Dry Film Thickness can be estimated on either magnetic surfaces (steel) or non-magnetic surfaces (metal), for example tempered steel or aluminum, with an Elcometer digital thickness gauge. The law of electromagnetic induction is utilized for non-conductive coatings on magnetic substrates like steel. The eddy current principle is utilized for non-conductive coatings on non-ferrous metals.
