Multi-electrode electrical resistivity & induced polarization imaging instruments

The main difference between electrotomography and classical vertical electrical sounding is the use of multi-electrode electrical prospecting braids and full automation of measurements.

Method of 2D/3D resistivity imaging allows you to solve a wide range of problems with a high degree of economic efficiency. A detailed study of the structure of the soil to a depth of several hundred meters, exploration of ore minerals, mapping of the alluvial deposits, determining the topography of bedrock when designing the foundations of buildings, studying the state of industrial facilities such as dams, dams, tailings dumps, etc. Electrotomography is based on the use of multi-electrode electrical prospecting braids connected to equipment capable of switching current and measuring electrodes to arbitrary braid leads. This technology increases the productivity and resolution of studies by the resistance method by an order of magnitude, especially if the equipment has several measuring channels that allow measuring the potential difference simultaneously from several receiving lines.
