High Sensitivity Geophone 10Hz

High  Sensitivity Geophone 10Hz is a type of high precision and  low distortion geophone, which is more and more applied in 2D&3D seismic survey and vibration monitoring with single unit by replacing multi-geophone strings.  With the characteristic of high sensitivity, low distortion, light weight and easy deploying,  high sensitivity geophone 10hz is becoming a improved choice compared with conventional 10hz geophones.

  • GS One 10Hz equivalent and vertical direction.
  • High Sensitivity of 85.80V/m/s.
  • Low distortion less than 0.1%.
  • Geophone sensor, land cased geophone or marsh cased geophone optional.
  • Steel spike or snow flat plate base optional.
  • 3-year limited warranty exclusive of high voltage, lightening or physical abuse.
