B/200

B/200
  • WIDE BAND RESPONSE
  • LOW NOISE PERFORMANCE
  • ACOUSTIC REFERENCE STANDARD
  • OMNI BEAM PATTERN
  • HIGH PERFORMANCE
  • DOUBLE-SCREENED CABLE

The B/200 miniature hydrophone has been designed by Neptune to achieve the optimum combination of frequency, physical size and receive sensitivity. This has resulted in a hydrophone with a wide variety of applications ranging from marine mammal sound studies to the analysis of near field pressure patterns.

The B/200 is available with or without acoustic calibration which is traceable to National Standards.
