Nortek designs, develops and produces scientific instruments that apply the Doppler principle to underwater acoustics in order to measure water in motion, such as currents and waves.

We provide truly innovative, robust, and accurate instruments, backed up by advanced software and comprehensive support to ensure customers maximize value from their measurements.

Our solutions make a big difference.

These instruments are used by scientists, researchers and engineers at renowned institutions and government agencies worldwide. They are employed in demanding environments that require state-of-the-art instrumentation that is reliable and easy to use.

Our exploratory devices help cast light on the workings of the world’s oceans, which occupy vast swathes of the planet, but are still little understood.

Most of Nortek’s technology is based on a scientific physical principle called the Doppler effect. This relates to the change in frequency (or pitch) when a sound source moves with respect to an observer.

By measuring these changes in frequency/phase, our instruments accurately measure profiles of speed and direction of complex water motion.

Nortek’s product portfolio ranges from wave measurement systems to single-point turbulence sensors and oceanic current profilers. Our product range covers four themes: ocean waves, ocean currents, turbulent flow and subsea navigation.

Our objective is to excite users with useful, innovative technology underpinned by oceanographic science and research. We work systematically with quality and are certified by leading quality assurance organizations.
