Our hydrophones are precision instruments: and the research institutes, companies and military outfits that we work with demand nothing less.
From oceonographic research to monitoring industrial processes, we have a range of hydrophones for reference measurement, reference projectors, passive arrays, positioning systems and tracking systems. And if you cannot find the right hydrophone, we’ll work with you to develop a solution that meets your specific needs.
