VAS-200

VAS-200 geophone is kind of low frequency geophone with high sensitivity developed following request of seismic exploration and engineering which is mainly to receive deep level, low frequency and weak signal. It can be used as single point and also 3- component
  • - High sensitivity: 220 V/m/s
  • - Low Frequency: 4.5Hz
  • - High SNR and wide dynamic range
  • - Low distortion
  • - Vertical and horizontal available
