Waterproof and highly resistant to corrosion, Brel & Kjr's hydrophones are suitable for use in water, liquids or gases. Each individually calibrated microphone contains a flat frequency response and provide omnidirectional measurements over a wide frequency range.

Four available versions offer different features to suit the varied, rigorous tests that hydrophones are typically used for in industrial or laboratory experiments, such as ultrasonic or high frequency testing. They can also be used for many other types of aquatic tests, including acoustic studies of marine animals, underwater projection and noise measurements in humid or polluted atmospheres.
