Product Description:Rugged build quality with high-end ADV® performance is what the ADVOcean-Hydra is all about. Representing the ultimate solution to measuring precise 3D velocity in the most challenging environments, the ADVOcean/Hydra can be integrated with an array of external sensors for a complete oceanographic data collection system. With the optional RPT pressure sensor, this powerful system is able to sample both pressure and velocity at up to 25 Hz, making it the definitive solution for studying nearshore processes.
