D-2 Inc. has developed a high-performance CTD (Conductivity, Temperature, Depth) profiler designed for precision oceanographic measurements across a wide range of platforms. Find out more > >
Engineered with a flow-through closed field conductivity cell, this compact and low-power instrument is ideal for full ocean depth profiling applications, delivering accurate data without the need for an external pump.
The profiler features an ultra-efficient 4 mA power draw, a sample rate configurable between 2 and 30 Hz, and provides real-time data output via RS-232 or USB-C. With onboard memory and an internal battery, it can operate independently, storing data for later retrieval or transmitting it live, as demonstrated in a recent deployment where 1,000 meters of continuous data was sent via Iridium satellite. The sensor arrives fully calibrated and ready to integrate, requiring minimal space and setup.
Available in aluminum housings rated to 3,000 meters or titanium versions rated to 11,500 meters, the D-2 CTD Profiler is field-tested, durable, and highly customizable. Its closed field design offers unmatched precision in a small footprint, making it a unique solution for OEM integration and fast deployment at a competitive cost.
