Offshore Geophysical Hydrophone and dual sensors

SF-25

SF-25 hydrophone is a piezoelectric geophone used in seismic exploration in transitional zone, swamp and shallow water. It has the characteristics of small volume, good sealing and waterproofing, high sensitivity and so on.
  • - Stable output and good consistency. 
  • - Low impedance 
  • - Perfect waterproofness and strong protective cover available
