Product Description
Low Frequency Geophone 2Hz Sensor Horizontal EG-2-II
The geophone 2Hz has good parameter consistency, firm mechanism, good tightness, high sensitivity, low distortion, reasonable damping coefficient, and high resolution, which can meet the requirements of multiwave component seismic data acquisition technology.
Working frequency bandwidth ：2Hz - 200 Hz
The Seismic geophones 2Hz are mainly used for deep seismic surveys, advanced predictions, natural seismic surveys, pulsating microseismic measurements of bridges, dams, highways and railways, and safety monitoring.
