Omnidirectional Spherical Hydrophone
BII7000 Series Omnidirectional Spherical Hydrophone
BII's spherical hydrophones provide omnidirectional responses up to 700kHz, and offer excellent acoustic characteristics of low noise and durability, which make these hydrophones ideal for a wide range of oceanography applications. Bespoke built-in preamplifiers allow the hydrophones to be used with long extension cables with no loss in sensitivity. The customized built-in filters increase Signal-to-Noise Ratio, reject unwanted noise and avoid saturation.
