2Hz Seismic Geophone Vertical Waterproof Land Case
Seismic Geophone has various advantages such as simple structure, high firmness and wide frequency range;
Low Frequency Geophone 2Hz Sensor
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.
