SwiFT Deep CTD

The SWiFT Deep CTD profiler provides direct survey-grade measurement of conductivity, temperature and depth, as well as computed salinity, density and sound velocity, and includes a GNSS receiver for accurate geo-location. Featuring a fast response temperature probe and housed in a robust titanium enclosure, it can be deployed at depths down to 6000m, and includes a rugged deployment cage.

The SWiFT Deep CTD has been designed with ease of use foremost in mind, featuring Bluetooth® wireless communications for fully-automated data transfer as well as USB and serial, as well as a magnetic switch ring that is easy to operate even with cold hands. The unit provides an operational battery life of up to five days and can be charged via USB.
