GS One Geophone Sensor (Equivalent)
GS One geophone sensor(P/N: ST-10PA) is a type of high precision and low distortion sensor, which is more and more applied in 2D&3D seismic survey and vibration monitoring with a single unit by replacing multi-geophone strings.
With the characteristic of high sensitivity, low distortion, light weight and easy deployment, the ST-10PA geophone sensor is becoming an 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.
- Standard steel soil spike or snow flat plate base optional.
- 1-year limited warranty on basic elements exclusive of high voltage, lightening or physical abuse.
