Horizontale directiviteit
Hydrostatische druktest
Nadat de hydrofoon is onderworpen aan hydrostatische druktests van 2Mpa/1h, 0Mpa/0,25h, 2Mpa/1h en 0Mpa/0,25h, heeft de hydrofoon geen schade of afwijkingen aan de buitenkant en is de isolatieweerstand tussen de positieve en negatieve elektroden van de hydrofoon groter dan 200 megaohm, en is de isolatieweerstand tussen de positieve en negatieve elektroden en de afscherming groter dan 200 megaohm. megahm.
