Geophone Element

  • GS-20DX Geophone 10Hz, 14Hz, 28Hz, 40Hz, 60Hz, 100Hz

GS-20DX Geophone 10Hz, 14Hz, 28Hz, 40Hz, 60Hz, 100Hz

GS-20DX Geophone 10Hz, 14Hz, 28Hz, 40Hz, 60Hz, 100Hz 

The GS 20DX geophone is a conventional double-lead spring geophone with small error in operating parameters and stable and reliable performance. The structure is reasonable in design, small in size and light in weight, and is suitable for seismic exploration of strata and geological environments of different depths.
