AGI MiniSting Geoelectrical Instruments
Description
The AGI MiniSting is a high-power, single-channel induced polarization (IP) and electrical resistivity instrument used for groundwater investigations, land network studies, soil resistivity testing for corrosion protection design, and soil testing.
This instrument is designed for ease of use, light portability, low cost, and high accuracy, making it suitable for low-labor exploration, educational demonstrations, and training.
This instrument is recommended for Vertical Electrical Sounding (VES), profiling, the IEEE Fall-Off-Potential (FOP) method, and the four-pin Wenner soil test (ASTM G57) for soil resistivity.
