Dakota's ultrasonic thickness gauges are some of the toughest in the world, with gasket sealed aluminium housings and warranty periods of up to 5 years. They are commonly used to determine the thickness of a variety of materials non-invasively by making contact with only one site of the material being tested. Dakota Ultrasonics flaw detectors has the ability to detect very fine pits, flaws, and porosity in materials without having to destroy the material or parts being tested.

Their wide range of NDT units offers everything from the most basic single velocity gauge to highly accurate, data logging, multi-mode, material and coating thickness models with live visual displays. For specialised subsea applications, the Dakota UMX-2 is a high-spec submersible gauge designed for offshore inspections at depths of up to 300m.

Dakota Ultrasonics also manufactures a line of ultrasonic bolting equipment that very accurately measures the stress, elongation, and load in threaded fasteners.
