Founded in 1983, Cygnus pioneered the digital multiple echo technique. The technique has long since been the industry standard for accurate measurement of material thickness.

Driven by the need for a hand-held device they successfully developed multiple echo digital thickness gauges which measure metal thickness through protective coatings in a reliable and repeatable way.
