Measurement content:
Receive Sensitivity
Measuring the receiving sensitivity of the hydrophone in the 0.02kHz-20kHz frequency band.
Vertical Directivity
The vertical directivity opening angle of the hydrophone should meet 
, measurement frequency points is 5kHz, 10kHz, and 20kHz.
Receiving sensitivity
The receiving sensitivity of the hydrophone with a preamplifier (amplification 30dB) is as follows.
