Single Geophone Vertical in Land Geophone Case Without Connector, Seismic Refraction Survey Seismic Detector 4.5Hz

Product Description Geophone 4.5Hz Vertical without connector The geophone 4.5hz 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 spike 75mm, with 1m leader cable, terminated without connector.
