The D-2 Hybrid CTD is a unique oceanographic instrument based on patented conductivity sensing technology and cutting-edge solid state electronics and signal processing, combining the advantages of both electrode and inductive sensing techniques. This design approach has resulted in a smaller size and improved precision, and also allows the sensor to be free-flushed with no pump required for the majority of applications.
The Hybrid CTD offers a rich suite of features that is unparalleled by any other deep-sea solution on the market. High-speed sampling capabilities enable the user to select rates of up to 25 Hz, and a variety of third-party sensors can be integrated via A/D and serial interfaces. Data can be output via USB, RS-232 or RS-485, and can also be transmitted via a wire line using commercially available telemetry systems.
The rugged sensor can be provided in aluminum, stainless steel or titanium housings to meet different depth and environmental requirements. Specialized custom and OEM variants are also available.
