Classic conductivity, temperature, and pressure measurement in combination with flow velocity
The Net Probe is unique! It is the only CTD probe that is equipped with 2 Electronic Flow Meters for accurate measurement of flow velocity and volume data during plankton net operations. Ideal both for single-ring and double-ring plankton nets. Either to be used in online mode with long-distance telemetry via electro-mechanical towing cables or in self-contained mode with data recording inside its internal data memory.
The system consists of a titanium pressure housing with integrated conductivity, temperature, and pressure sensors, measuring electronics, 2 Electronic Flow Meters, and a Deck Command Unit. This is the link between the underwater unit and PC during online operations and displays the measuring data of the probe in clear text.
The power supply of the underwater unit is made of 3 long-time lithium batteries placed in an external removable battery pack. Batteries can easily be replaced without opening the main electronics housing which eliminates the risk of water ingress and corrosion of the electronics board. The state-of-the-art electronics, optimised in power consumption, are designed for ambient temperatures from -40°C up to +85°C.
The system is rated to a maximum operational depth of 3000 meters. The Net Probe is delivered with the data acquisition software OceanLab 3 – an easy-to-use package for pre-deployment system set-up, real-time data acquisition, data visualisation, storing, and export.
– Additional sensors of various parameters
– Operational depth down to 6000 meters
