Hydrophone Systems for
Research and Professional Audio applications
Cetacean Research Technology began manufacturing hydrophones originally for the research and professional audio community in 1994. We continue to offer a vast range of hydrophone systems designed to meet the demanding requirements of underwater acousticians, oceanographers, marine mammal scientists, fisheries biologists, audio engineers, fine artists, and anyone else requiring impeccable audio quality and a very broad frequency response. Because there are so many possible hydrophone system combinations, only our more common systems are listed on this page.
If you don’t see a system that meets your needs, please contact us and we will help put together the best hydrophone system for you.
The Cetacean Research™ C75-DR100-SP noise measurement system consists of of our ultra-wide bandwidth, omnidirectional Cetacean Research™ C75 hydrophone, aTASCAM DR-100 recorder and SpectraPLUS analysis software more
The Cetacean Research™ C75-200-SP underwater sound analysis and noise monitoring system consists of our ultra-broadband, omnidirectional, calibrated Cetacean Research™ C75 hydrophone, theSpectraDAQ-200 calibrated USB computer interface, and SpectraPLUS analysis software more
