Product Description
STARTER Geophone 4.5hz vertical with 4 pin male 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.
STARTER GEOPHONE 4.5 Hz vertical , lead cable 80 meters , 3 core cable , O.D 5.3 mm , terminated with 4 pin male connector.
