Caractéristiques principales :
- Convient pour des températures allant jusqu’à 100°C, résiste au décalibrage par des amplitudes de pression élevées
- Grande polyvalence grâce à un faible encombrement et une largeur de bande de mesure jusqu’à 10 MHz
- Hydrophone optique couplé à une fibre optique
- Immunité aux interférences électromagnétiques
