The B/200 miniature hydrophone has been designed by Neptune to achieve the optimum combination of frequency, physical size and receive sensitivity. This has resulted in a hydrophone with a wide variety of applications ranging from marine mammal sound studies to the analysis of near field pressure patterns.

The elimination of any metal components from the construction prevents corrosion and also reduces distortion of the sound field caused by scattering.

With its all-moulded construction, the B/200 is completely waterproof down to a depth of 500 metres.

Electrical connection is by a double screened, low noise coaxial cable with a polyurethane outer sheath.

The versatility of the B/200 is further enhanced by selecting materials for the hydrophone stalk and outer cable sheath that enable the hydrophone to be bonded or moulded directly into waterproof housings.

The B/200 is available as a calibrated or un-calibrated device with all calibrations traceable to National Standards.
