CTD Profiler - D-2 Inc. Full Ocean Capability

CTD Profiler - Full Ocean Depth Capabilities

CTD profiler built by D-2 Inc is a precise instrument used in Oceanography to measure Conductivity aka Salinity, Temperature, and Depth (CTD). The D-2 CTD Profiler is ideal for use in any Ocean profiling application and on any platform, offering flow through closed field conductivity measurement. The precision of a closed field cell, the benefits of a small flow through design. Extremely quiet, extremely low power, field tested and durable. These can be custom built into any existing profiling platform.

The image above is the OEM CTD Profilers we provided to Woods Hole Oceanographic Institution as part of the Ice Tethered Profiler Program for the Arctic Ocean, you can read more about that here: https://www.d-2.com/d-2-inc-ctds-live-in-arctic-ocean-on-ice-tethered-profilers-itp/

In the example above our CTD profiler takes samples for 1000 meters continuously, transmitting the data back via iridium satellite. This OEM CTD we provided uses extremely low power 4 mA, at 2 Hz sample speed and is built to fit perfectly into the existing profiler. Due to being closed field conductivity the sensor arrives calibrated and ready to install and use.

Our CTD’s can enhance your profiler’s abilities by taking much less footprint than any other closed field conductivity cell, requiring no pump, extremely quiet, yet delivering extremely precise data. No other CTD can offer both no pump, extremely low power and also closed field precision.
