Digital Hydrophone and Recorder Underwater Hydrophone for Noise monitoring and underwater Noise Recording The Digital Hydrophone captures underwater acoustic data for monitoring and recording. Deployment is flexible: connect to a personal computer, or integrate it into ROVs, AUVs, UUVs, or oceanographic buoys. It serves applications including commercial whale watching, industrial engineering, ambient noise monitoring, marine mammal observation, recreation, tourism, education, art, and research.
1.Multi-function: Combines traditional analog hydrophone, amplification and conditioning circuit, acquisition, storage, and Ethernet transparent exchange functions.
2. Fast cascading array: Two 100/1000Mbps self-adaptive Ethernet interfaces make it easy to quickly form a large-scale synchronous underwater acoustic measurement or observation processing system through cascading arrays.
3.High synchronization accuracy: uses PTP (IEEE1588) protocol for synchronous data collection and transmission between hydrophones via Ethernet, with automatic and fast synchronization after
power-on, and accuracy within hundreds of nanoseconds.
4.Low self-noise, large dynamic range, and high versatility.
5. Customizable working frequency band with fixed and adjustable gain range
