4.5 Hz Geophone Vertical in land case with Stainless steel disc base & Mueller clips connector
The geophone 4.5hz (EG-4.5-II) is a conventional type of moving coil geophone with small
error in working 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.
It is equivalent to SM-6 B coil 4.5hz geophone.
Widely used in industrial vibration-monitoring systems.
Ideal choice for shear-wave horizontal elements.
Single geophone 4.5Hz vertical in waterproof land case with Stainless steel disc base, with 1m leader cable, terminated with Mueller clips connector.
