SWiFT CTD

Designed for a Seamless Workflow

The new SWiFT CTD is the next generation of Valeport’s popular range of SWiFT profilers and delivers enhanced accuracy and versatility for those requiring CTD measurements.

Description

Measured CTD with all the benefits of the SWiFT

The new SWiFT CTD profiler provides survey-grade sensor technology coupled with the convenience of Bluetooth connectivity, a rechargeable battery and an integral GPS module to geo-locate each profile. Ease of use is at the heart of the SWiFT range and the new SWiFT 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 status indications for GPS, battery and communications.

Enhanced accuracy

Using Valeport’s world-leading high-accuracy sensor technology to combine sensors for multiple profiles in a single drop, the SWiFT CTD features a new fast response temperature probe and operates down to 500m as standard, delivering directly measured Conductivity, Temperature and Depth. In addition, the SWiFT CTD will provide computed Salinity, Density and Sound Velocity..

SOFTWARE

Download and review data with Valeport Ocean

Data can be quickly and easily downloaded wirelessly and uses Valeport’s new Ocean software for Windows, iOS and Android. Data can be instantly shared in industry-standard data formats.

Multiple Applications

With an operational battery life of up to five days and the convenience of charge via USB, the SWiFT CTD is intended for offshore, coastal, harbour and inland environmental and hydrographic survey use. The SWiFT CTD is robust and portable. Constructed from titanium to provide unmatched durability, the CTD sensors are housed in a strong acetal protective cage.  An optional deployment cage is also available to bolt onto the instrument to help get the SWiFT CTD to depth in fast-flowing currents.
