Ujian tekanan hidrostatik
Selepas hidrofon telah menjalani ujian tekanan hidrostatik 2Mpa/1j, 0Mpa/0.25j, 2Mpa/1j dan 0Mpa/0.25j, hidrofon tidak mempunyai kerosakan atau kelainan di luar, dan rintangan penebat antara elektrod positif dan negatif hidrofon adalah lebih besar daripada 200 megohms dan rintangan negatif antara perisai positif dan negatif. 200 megohm.
