Aanderaa has from the very beginning been known for its capability of supplying complex system solutions – often with a combination of submersible sensors and sensors in air, real time transfer of data via radio, GPRS or satellite and the data displayed on a single screen or via a web server.

The sensor platform may be a submersible data logger, a Current Meter or a Data Buoy on the surface.

The SmartGuard data logger is a versatile data logger that combines data from submersible sensors as well as sensors on land. The logger accepts different data formats from Aanderaa sensors as well as from sensors made by other suppliers.
