This light and handy measuring instrument provides accurate pressure data during operations of plankton nets, water samplers and other sampling equipment in limnological and oceanographic applications. It can be used in online mode with integrated long-distance telemetry via electro-mechanical towing cables as well as in self-contained mode with data recording inside its internal data memory.
The system consists of a titanium pressure housing with integrated sensor, electronics, rechargeable batteries. A splash-proof hand unit is the link between underwater unit and PC during online operations. The state-of-the-art electronics, optimised in power consumption, are designed for ambient temperatures from -40°C up to +85°C.
The maximum operational depth is 3000 meters. The Depth Meter 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.
