Aanderaa SeaGuard RCM

The single-point SEAGUARD® RCM series is a completely new generation of current meters based on the SEAGUARD® datalogger platform and the ZPulse® multi-frequency Doppler Current Sensor (DCS). SEAGUARD® Products are based on modern technology and are the basic modules of our underwater observatory. They may be used as a multi-parameter instrument in the sea and in freshwater and feature a modular plug-and-play architecture.
