Designed for a seamless workflow.
The new SWiFT CTDplus Turbidity is the latest in Valeport’s popular range of SWiFT profilers and delivers enhanced accuracy and versatility for those requiring combined CTD measurements and Turbidity observations.
Measured CTD with all the benefits of the SWiFT
The new SWiFT CTDplus Turbidity 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 CTDplus Turbidity 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.
Using Valeport’s world-leading high accuracy sensor technology to combine sensors for multiple profiles in a single drop, the SWiFT CTDplus Turbidity features a new fast response temperature probe and operates down to 500m as standard, delivering directly measured Conductivity, Temperature and Depth with Turbidity observations. In addition, the SWiFT CTDplus Turbidity will provide computed Salinity, Density and Sound Velocity.
Valeport’s Turbidity technology is essentially two sensors in one. The first is a “classic” nephelometer, using a 90˚ beam angle for turbidity levels between 0 and 2,000 NTU. The second sensor uses Optical Backscatter (OBS) for turbidity levels up to 10,000 NTU. The sensors output data separately and simultaneously at a programmable rate. This means that there is no need to switch ranges as conditions vary. Intelligent sampling and the use of a 24 bit ADC eliminates the need to switch gain.
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.
With an operational battery life of up to five days and the convenience of charge via USB, the SWiFT CTDplus Turbidity is intended for offshore, coastal, harbour and inland environmental and hydrographic survey use.
The SWiFT CTDplus Turbidity 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 secure additional weight and so help the SWiFT CTDplus Turbidity get to depth in fast-flowing currents.
