Horisontale rigting
Hidrostatiese druk toets
Nadat die hidrofoon aan 2Mpa/1h, 0Mpa/0.25h, 2Mpa/1h, en 0Mpa/0.25h hidrostatiese druktoetse onderwerp is, het die hidrofoon geen skade of abnormaliteit aan die buitekant nie, en die isolasieweerstand tussen die positiewe en negatiewe elektrodes van die hidrofoon is groter as 200 megohms en die positiewe weerstand en die negatiewe elektrodes. meer as 200 megohm.
