TERRAMETER SAS 4000 Combined IP and Resistivity System
  • High accuracy due to 24 bit BITSTREAM A/D conversion and up to 140 dB dynamic range plus 64 dB automatic gain control.
  • Thousands of measurements can be stored in vast internal memory.
  • System capable of controlling external transmitters.
  • Compact and self-contained with integrated receiver and transmitter.
  • Easy to operate, with large LCD display and menu-driven operation.
  • High measuring capacity with four input channels. Makes four readings at the same time when used with the ES 10-64 resistivity imaging electrode switching system.
  • Time-domain IP - measures chargeability in user-selected time intervals.
