Wave Buoy

Wave Buoy

Offshore wave buoy is a long-term and automatic wave measurement buoy system, which transmits the measurement data to the shore station and store the data in the buoy. This wave buoy is suitable for the use of marine environmental monitoring station, for the use of preliminary investigation of marine engineering and also can be used for some special needs.
