EM1401 non-contact thickness gauge measures thickness of steel pipes, tanks, flat steel and other steel constructions, together with constructions made of aluminium and other metals. Measurements can be taken without usage of couplant, without advance surface preparation and across the operating gap between the transducer and the test object of up to 6 mm. Rust film, salt deposits or any other insulating coat (paint, varnish, enamel, plastic etc.) can serve as an operating gap.

Test indications are slightly dependable on the skew of the transducer, unlike tradition thickness gauges with piezoelectric converters, which require fixating transducer at the specific position.

EM1401 has a bright colour display that allows user to view A-scan.

EM1401 has three thickness measurement modes:
– automatic;
– manual mode, measurements are made using maximum in the first gate;
– manual mode, measurements are made using two maximums in two gates.
