H-Instruments designs and produces specialized equipment for underwater sound and environmental measurement.

We focus on hydrophones and underwater sensing solutions used in marine research, field recording, and technical applications where reliable data matters.

Our team has over 30 years of experience in designing, building, and testing electronic instruments, with academic backgrounds in electronics (BSc and MSc). This expertise allows us to develop high-performance systems tailored for real-world underwater environments.

We design and manufacture our own products, with a strong focus on signal quality, low-noise performance, and practical usability in the field.

With deep knowledge of analog and digital signal processing,

 we turn underwater signals into meaningful data —

helping our customers capture, analyze, and understand the hidden world beneath the surface.

Hydrophones and tools for capturing underwater sound

H-Instruments makes and sells hydrophones for anyone who wants to record what happens below the waterline. From quiet lakes to open sea, our gear is built to bring underwater sound up to your recorder.

Pair a hydrophone with our hydrophone amplifiers and phono adapters to connect with the equipment you already use. Remote temperature logging sits alongside it, so you can track the water as well as hear it.

Whether you are recording for research, curiosity or creative work, explore the range and start listening.
