Oceanographic Parameters

Oxygen Sensor

The Oxygen optode is designed to measure absolute oxygen concentration and % saturation. The optode can be used from streams to deep sea, from fish farms to waste water and from polar ice areas to hydrothermal vents.  The lifetime-based luminescence quenching principle offers the following benefits: Response time <8 sec (63%) High accuracy Not stirring sensitive …

In-line ZPulse Doppler Current Sensor

The In-line Doppler Current Sensor (DCS) is the first current sensor with the option to directly connect water quality sensors in a robust, integrated package (version 5810). The sensor replaces the successful DCS4100 in-line current sensor using newer technology with extending capabilities. It is designed for easy integration into systems …

Current Sensors

The Current Sensors are based on the backscatter acoustic Doppler principle. The Current Sensors has two orthogonal transducer axes with two transducers on each axis. This enables the Current Sensors to measure in both directions on each axis which is a great advantage. This makes it insensitive to disturbance from vortex speeds …

Temperature Sensor

The Temperature Sensor is an intelligent sensor designed to be used on Aanderaa SeaGuard Platform as well as in other measurement systems (RS232). The sensor is based on a thermistor-bridge. A Digital Signal Processor controls the sampling of the bridge and calculates the calibrated temperature in engineering units. The sensor …

Turbidity Sensor

The Turbidity Sensor is based on the Seapoint Turbidity Meter. The sensor detects light scattered by particles suspended in water. This measurement is known to have a good correlation to the amount of suspended matter in water and can be used to monitor e.g. sediment, algae or particle pollution. The sensor …

Conductivity Sensor

For seawater, the ability to conduct electrical current is mostly dependent on temperature and the amount of inorganic dissolved solids. Salinity is defined as the concentration of dissolved solids. This means that, together with temperature and depth information, a good estimate of the salinity may be determined. By using the …

Wave and Tide Sensor

The tide measurement is an average of the hydrostatic pressure measured over a time period of 10 seconds to 8 minutes (integration time configurable by the user). The update interval is between 1 second and 255 minutes. The wave meassurements are based on the pressure time series measured over a …
