High Frequqncy 60Hz Reinforced Geophone for Land, Desert, Snow, Marsh and TZ

High frequency 60Hz geophone (ST-20DX,60Hz) in vertical direction (P wave) and horizontal direction (S wave) are available, which are suitable for deep seismic exploration, advance perdiction, natural seismic survey, pulsating microseismic survey of bridges, dams, highways and railways, safety monitoring, engineering pulse measurement and other vibration analysis.

● Good parameter consistency.

● Firm mechanism structure.

● Good sealability.

● Suitable for multi-wave component seismic data acquisition.

● Different type of geophone cases which are suitable for land,desert, snow, marsh and transition zone respectively.

●3-year limited warranty on basic element exclusive of high voltage, lightening or physical abuse.

We supply 60hz geophone coil, geophone element, geophone sensor, single geophone and geophone array with KCK connector, KCL connector, 408 connector, Kooter connector, MP16 connector, Split spring connector and Mueller clip connector optional as the lead connector. Lead wires from O.D 4.6mm to O.D 7.8mm available.

● Customized geophone connector and lead wire applicable upon request.
