Teledyne RDI Citadel CTD Products

After years as a Doppler manufacturer, we’ve stepped outside of our core technology via the introduction of our new Citadel CTD (Conductivity, Temperature, and Depth) product line.

In May of this year, Teledyne RDI purchased the entire line of Conductivity, Depth, and Temperature (CTD) products from Falmouth Scientific Incorporated (FSI), including the patented Non-external Inductive Cell (NXIC), which has already acquired a solid reputation for robust operation in shallow, fouling environments.

This product line delivers exciting and proven technology that is complementary to Teledyne RDI’s ADCP products, and represents a tremendous opportunity for us to quickly expand our product offerings and deliver turn-key solutions to our worldwide customer base.

CTDs are used extensively around the globe for the measurement of temperature and salinity, but also for the important derived parameters of density and speed of sound. They are used for academic, commercial and defense applications; and are often used in concert with ADCPs to gain a clearer understanding of the ocean’s complex physical environment.

Are you a CTD user?
