High Sensitivity Geophone 5Hz (EG-5-HS-I) is used to receive the weak deep and low frequency signal. This kind of geophone has following characters: Low frequency, Low distortion and high sensitivity. It’s suitable for field single point data acquisition. It is a long coil travel version geophone with high sensivitivy of 80.0V/m/s. The extra coil travel offers an advantage for higher tilt requirements and where larger amplitude signals may be encountered, for example, in industrial vibration monitoring.
