Valeport Unveils 6000 m Rated ‘Deep’ CTD

Valeport’s popular range of SWiFT profilers has been extended with the launch of a new addition for those requiring CTD measurements to depths of 6000 m.

Offering increased versatility and absolutely no compromise on accuracy, the new SWiFT Deep CTD has been designed with the intention of a seamless workflow and offers the highest quality CTD profiles in a compact, robust, and portable package.

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

Using Valeport’s world-leading high-accuracy sensor technology to combine sensors for multiple profiles in a single drop, the SWiFT Deep CTD can operate to 6000 m, 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. Data can be quickly and easily downloaded wirelessly and instantly shared in industry-standard data formats.

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 but delivers fully automated data transfer with no user input required and features Valeport’s signature SWiFT magnetic switch ring. The switch 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 GNSS, battery, and communications.

With an operational battery life of up to five days and the convenience of charge via USB, the SWiFT Deep CTD is designed to cope with the harshest conditions and is intended for offshore, coastal, harbor, and inland environmental and hydrographic survey use.

Providing unmatched durability, the SWiFT Deep CTD is constructed from titanium, and the CTD sensors are housed in a strong acetal sensor guard.
