Hydrophones

The Brüel & Kjær range of hydrophones is a range of individually calibrated, waterborne‐sound transducers that have a flat frequency response and are omnidirectional over a wide frequency range. Their construction is such that they are absolutely waterproof and have good corrosion resistance.

TYPE 8103

Miniature hydrophone with integral 6m cable terminated 10-32UNF microdot plug
Suitable for high-frequency laboratory and industrial use and particularly for the acoustic study of marine animals or for cavitation.
TYPE 8104

Standard measuring hydrophone with integral 10m cable terminated BNC plug
A general purpose hydrophone, also ideal for calibration purposes
TYPE 8105

Spherical hydrophone with 10m integral cable terminated BNC plug
A robust spherical hydrophone usable down to 1000 m ocean depth with excellent directional characteristics.
TYPE 8106

Hydrophone
Has a built-in amplifier which gives a signal suitable for transmission over long cables. It is usable down to 1000 m ocean depth.
