Ultra low-noise wide band hydrophone

The H507A wide band (10 Hz to 100 kHz) hydrophone is a very small, high-sensitivity device incorporating an ultra-low noise preamplifier (-166 dB re 1V/√Hz at 10 kHz) and a circuit for the insertion of an electrical calibration signal. In addition, the preamplifier can drive up to 200 meters of cable. The sensor and amplifier are electrostatically shielded and molded in hydrolytically stable, void free polyurethane.
