Oceanographic buoy REMHY

special mark

REMHY is a Wi-Fi surface buoy that leads the way to a new range of application for underwater noise measurements. It can simultaneously acquire data from 4 wide-band hydrophones of variable cable length. This buoy accepts both passive and preamplified active hydrophones and its wide band analog input allows up to 1 MHz with a dynamic range greater than 100 dB therefore guaranteeing an efficient signal to noise ratio. The embedded digital signal processor allows high speed acquisition filtering while users can stream data and launch or stop recordings up to a distance of 700 m. REMHY can be easily deployed and recovered by a single person.
