D/70

D/70
  • OMNI-DIRECTIONAL RESPONSE
  • LOW NOISE PERFORMANCE
  • ACOUSTIC REFERENCE STANDARD
  • BROADBAND OPERATION
  • AIR GUN & BOOMER MONITOR
  • MARINE MAMMAL AUDIO SENSOR

The all moulded construction and inherent strength of the PZT ceramic sphere achieves a robust, light weight, corrosion free design making it the ideal choice as a monitor hydrophone for air gun, boomer and other environments where high levels of shock are experienced. 

The D/70 is available with or without acoustic calibration which is traceable to National Standards.
