MiniSting™ R1

The MiniSting™ R1 is a high-powered, induced polarization (IP) and electrical resistivity instrument used for testing grounding grids, soil resistivity testing for corrosion protection design, and more. This single-channel tool is engineered to be the best tool for manual resistivity jobs—ease of use, low cost, and high accuracy make it ideal for low-manpower explorations and educational and training demonstrations.

MiniSting Geophysical Instrument for Resistivity/P/SP

Use Cases:

The MiniSting™ is versatile enough for both water and earth uses, including:

  • Cathodic Protection Design

  • Grounding Studies

 

Features:

  • This high-powered, lightweight tool has a built-in rechargeable NiMH battery—you can get a day’s worth of manual surveying from one charge. The system includes a battery charger.

  • An easy-to-use, menu-driven system. Recorded data is saved in the internal memory and at a convenient time downloaded to a computer for further processing. Our utility software, The Administrator, is included with the MiniSting™ as well as a serial download cable with a USB adapter. The Administrator software is used for data download.

  • Rugged construction. Whether you’re working in the swamp or the desert, the MiniSting™ is versatile enough to withstand harsh climates and provide accurate data.

  • The MiniSting™ reports in feet or meter: For example, the Wenner 4-pin method is typically specified for Wenner spacing in feet, but the reporting is required in Ohm Centimeter. Simply set the MiniSting™ for feet before surveying, and switch to meter after the survey before you download the data. Then move the decimal point two steps to the right to get Ohm Centimeter. This instrument can be configured in several ways depending on what you are measuring.

  • Pairs seamlessly with AGI tools for immediate results. For example, you can get more from your data when you pair the MiniSting™ with the EarthImager 1D—in addition to empirical calculations, you’ll also get modeled calculations that represent true resistivity, layer thickness, and depth to each layer so you can use your results and immediately take next steps with certainty.

The MiniSting™ is preprogrammed in manual measurement mode for the following arrays:

  • Wenner*

  • Schlumberger*

  • Dipole-Dipole*

  • Pole-Dipole*

  • Pole-Pole*

  • Mise-A-La-Masse*

  • Self-Potential (SP)*

  • Resistance

  • Azimuthal

AGI Active Electrode Cables

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
