Electrical Resistivity Tomography

Electrical Resistivity Tomography is a non-destructive practice in which an array of electrodes (typically 64) is used and connected by a cable containing multiple cores to get a subsurface investigation, or pseudosection, of the variation in resistivity, along with the survey line and below the surface both. Though it’s not as famous as ground penetrating radar (GPR), still it has its benefits and can be very useful in certain situations. If you are looking for Electrical Resistivity Tomography in India then you are at the right place.

ERT necessitates the measuring of the evident electrical resistivity of subsurface materials. During the course of an ERT survey, the electrical current is inserted into the earth via a pair of current electrodes, and the possible difference is calculated between a pair of potential electrodes.
