Reinforced Geophone 10Hz for Land, Desert, Snow, Marsh and TZ

Reinforced geophone 10Hz (ST-10N) is designed equivalent to SM-4 structure, which is for low weight, long field-life,and ultra reliable performance. Precision engineered components and computerized test equipment ensure consistency in manufacture and operation throughout and beyond the limited replacement guarantee period of three years.

  • Precision machine, rotating coil design.
  • Precious metal contacts for consistent reliable &prolonged field performance.
  • Vertical and Horizontal elements are available and also suitable for for 3-C applications.
  • Could be supplied as geophone sensor, geophone element, land case geophone, marsh case geophone or multi-geophone string.
  • Geophone cases for land, desert, snow, marsh and transition zone are available with steel spike or brass spike optional.
  • Various geophone connectors such as Split Spring Clip, Mueller Clips, Kooter, KCL, KCK, 5515, SH17WCR and other customized geophone connectors are available.
  • Assorted geophone cables is optional as per client’s request.
  • Widely used in structural and industrial monitoring system.
  • 3-year limited warranty on basic element exclusive of high voltage, lightening or physical abuse.
  • For 2-D and 3-D seismic exploration with bandwidth from 10Hz up to 190Hz.

Other type of of reinforced geophone 10Hz  like SM24 structure, GS-20DX structure, GS-32CT structure, GS One structure and SG10 are also available.
