The EM4000 EMA thickness gauge is designed for thickness measurement on steel pipes, sheet metal, rods, and other products made from steel, aluminum and other metals, with a operating gap of up to 3 mm between the sensor and metal. Operation of the EMA thickness gauge requires no preliminary surface preparation, no couplant is required. The gap can consist of dirt, layer of rust, layer of salt deposits or other non-conductive coating (paint, varnish, enamel, plastic, etc.). In addition to measuring metal thickness, the EM4000 allows measuring the thickness of non-conductive coating on metal.
