High Sensitivity Geophone 10Hz

High Sensitivity Geophone 10Hz is a type of high precision and low distortion geophone, which is more and more applied in 2D&3D seismic survey and vibration monitoring with single unit by replacing multi-geophone strings. With the characteristic of high sensitivity, low distortion, light weight and easy deploying, high sensitivity geophone 10hz is becoming a improved choice compared with conventional 10hz geophones.

GS One 10Hz equivalent and vertical direction.
High Sensitivity of 85.80V/m/s.
Low distortion less than 0.1%.
Geophone sensor, land cased geophone or marsh cased geophone optional.
Steel spike or snow flat plate base optional.
1-year limited warranty exclusive of high voltage, lightening or physical abuse.
