AGI’s Active Dual-Mode Electrode Cables (U.S. Patent 6,404,203) are used for ultra-sensitive automatic induced polarization (IP) measurements using nonpolarizable electrodes. The dual-mode electrodes have a receiver channel that is isolated from the transmitting stainless steel electrode.


Use Cases:

There are two main applications for dual-mode electrode cables:

  • Mapping of dense nonaqueous phase liquid (DNAPL) spills in the ground. Such as:

    • Methylene chloride, used in processing chemicals and pharmaceuticals.

    • Perchloroethylene, used in dry cleaning and metal surface cleaning.

    • Trichlorethylene, used in refrigeration and HVAC systems.

  • Mineral exploration


Product Features:

  • Thick transmitter wires.

  • Receiver wires are electrically shielded from the transmitter for a noise-free measurement.

  • Internal kevlar-strength member.

  • Distributed switching instead of a centralized switching box allows for thicker wires which will output more current.

  • Transmits through the stainless steel stakes and receives through the non-polarizable electrodes for more sensitive measurements, especially during induced polarization (IP) surveys.

  • Dual-mode electrodes with a patented separate receiving channel.

  • Water-resistant.


Benefits Of Distributed Electrode Switching:

  • Connect the instrument anywhere along the electrode cable

  • No Switch Box needed

  • Easier to perform roll-along survey without a switch box

  • More depth penetration due to much less saw-tooth overlap pattern

  • Thick transmitter conductors

  • Shielded receiver conductors

  • Two modes of operation:

    • Normal mode: collect data using only stainless steel electrodes

    • Dual mode: transmit on stainless steel electrodes and measure on separate non-polarizable electrodes
