Hydrophones and tools for underwater sound recording
H-Instruments makes and sells hydrophones for capturing the sounds that live below the waterline, from quiet currents to distant marine life. Our range also includes hydrophone amplifiers and phono adapters, so you can connect your recording gear with ease.
Need to keep an eye on conditions as well? Our remote temperature logging lets you track water temperature without being on site, so your recordings and your data tell the full story.
