A wide-range general purpose hydrophone that can also be used as a sound transmitter, making it ideal for calibration purpose. The hydrophone is supplied with 10 m waterblocked low-noise shielded cable to MIL-C-915 with BNC plug.

Miniature Hydrophone Type 8103 A small transducer with a high sensitivity relative to its size and good all-round characteristics; applicable to laboratory, industrial and educational use. Its high?frequency response is valuable when measuring pressure-distribution patterns in ultrasonic-cleaning baths, for example.

• 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

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.

Type 8104 Standard Calibration Hydrophone can also be used as a sound transmitter (projector) which makes it ideal for calibration purposes by the reciprocity, calibrated-projector, and comparison methods.
