Factory directly sale 4.5 Hz to 100Hz Geophone for Seismic Refraction and reflection Vertical and Horizontal Geophone
The geophone is a device that converts ground movement (velocity) into voltage, which may be recorded at a recording station. The deviation of this measured voltage from the base line is called the seismic response and is analyzed for structure of the earth.
