8104  Standard Measuring Hydrophone with integral 10m cable terminated BNC plug

Uses Calibration reference standards  Ultrasonic measurements in liquids  Cavitation measurements  Laboratory and industrial measurements in liquids and gases  As underwater projectors (8103, 8104 and 8105)  Noise measurements in humid and polluted atmospheres

Features Frequency ranges from 0.1Hz to 180 kHz  Individually calibrated  Flat frequency response over wide range  Omnidirectional over wide frequency range Working pressures up to 9.8 × 106 Pa (100 atm. [1000 m])  Shielded-element construction Highly corrosion resistant

A wide-range standard measuring transducer for making absolute sound measurements over the frequency range 0.1Hz to 120 kHz with a receiving sensitivity of −205 dB re 1V/μPa. It can also be used as a sound transmitter (projector) which makes it ideal for calibration purposes by the reciprocity, calibrated-projector and comparison methods. The main features of Type 8104 are shown in Fig. 2.
