Designed for a seamless workflow. The new SWiFT Deep CTD is the latest in Valeport’s popular range of SWiFT profilers and delivers enhanced accuracy and versatility for those requiring CTD measurements to depths of 6000m.


Measured CTD with all the benefits of the SWiFT

The new SWiFT Deep CTD profiler provides survey-grade sensor technology coupled with the convenience of Bluetooth® wireless technology, rechargeable battery and an integral GNSS module to geo-locate each profile.

Ease of use is at the heart of the SWiFT range and the new SWiFT Deep CTD not only makes any problematic battery changes a thing of the past and delivers fully-automated data transfer with no user input required, it also features Valeport’s signature SWiFT magnetic switch ring. The switching ring is easy to operate even with cold hands, it simply turns through 90 degrees and reassuringly clicks into position. The end cap features user-friendly LED indications for operational status, GNSS, battery and Bluetooth® wireless technology.

Enhanced accuracy

Using Valeport’s world-leading high-accuracy sensor technology to combine sensors for multiple profiles in a single drop, the SWiFT Deep CTD features a new fast response temperature probe and operates down to 6000 m as standard, delivering directly measured Conductivity, Temperature and Depth. In addition, the SWiFT Deep CTD will provide computed Salinity, Density and Sound Velocity, calculated using the UNESCO international standard algorithm and Chen and Millero equation.
