A small, high-sensitivity hydrophone for absolute sound measurements over the frequency range 0.1Hz to 180 kHz with a receiving sensitivity of −211 dB re 1V/μPa. Type 8103 miniature hydrophone has a high sensitivity relative to its size and good all-round characteristics, which make it generally applicable to laboratory, industrial and educational use.

The high frequency response of this hydrophone becomes especially valuable when making acoustic investigations of marine animals, and for measuring pressure-distribution patterns in ultrasonic-cleaning baths.
