The Aanderaa SEAGUARD® String System is a complete and flexible subsea observatory, for measurements of e.g. dissolved oxygen, conductivity, temperature, current, pressure and tide.

SEAGUARD® String Logger
The Aanderaa SEAGUARD® String Logger is the basic module of the SEAGUARD® String System.The SEAGUARD® String Logger is capable of handling a large number of sensors. Data is stored on an internal SD-card or transferred in real-time via cable.  

SEAGUARD® Sensor String
The new Aanderaa SEAGUARD® Sensor String is designed to be connected to the SEAGUARD® String Logger.The SEAGUARD® String System can hold up to 25 AiCaP Sensors. Real-time communication and control is available using the Aanderaa Real-Time Collector.
