Horizontal directivity
Hydrostatic pressure test
After the hydrophone has been subjected to 2Mpa/1h, 0Mpa/0.25h, 2Mpa/1h, and 0Mpa/0.25h hydrostatic pressure tests, the hydrophone has no damage or abnormality on the outside, and the insulation resistance between the positive and negative electrodes of the hydrophone is greater than 200 megohms, and the insulation resistance between the positive and negative electrodes and the shield is greater than 200 megohms.
