100Hz Geophone for Coal Mine Prospecting

100Hz Geophone is an ideal choice for shallow seismic survey and it is mostly widely used in coal mine geological prospecting and exploration with the following features:

  • Good parameter consistency.
  • Firm mechanism structure.
  • Excellent sealing & stability.
  • Reinforced casing suitable for land ,snow, marsh and transition zone with Steel spike or Brass spike optional.
  • Assorted geophone connectors and geophone cables are available.
  • Compatible with various main stream seismographs such as Geometrics Geode, Strata Visor, Summit, PASI GEA24 and etc.
  • Also Suitable for multi-wave component seismic data acquisition.
  • 3-year limited warranty on basic element exclusive of high voltage, lightening or physical abuse.

We supply 100Hz geophone sensor, geophone element, land cased geophone, triaxial geophone and multi-geophone string with KCK connector, KCL connector, 408 connector, Kooter connector, MP16 connector, Split spring connector or Mueller clip connector. Lead wires from O.D 4.6mm to O.D 7.8mm available.
