Product Description

2D Geoelectric Electrical Topography System Resistivity/IP Meter With Resistivity Cables and Electrodes

2D Geoelectric Electrical Topography System Resistivity/IP Meter With Electrodes 0

Geoelectric electrical topography is the branch of Geophysics that deals with the behavior of rocks and sediments in relation to electric current. That is, they are those that study the response of the terrain when direct electric currents (DC) propagate through them. The physical parameter that is controlled is resistivity and the final interpretation is made based on the geological characteristics of the area in which geoelectric prospecting methods are applied:

 

ELECTRICAL TOMOGRAPHY Equipment is a direct current method system whose purpose is to determine the variation of the electrical resistivity of the subsoil as a function of depth and along a profile, that is, in 2 dimensions (2-D).

 

In the Dipole-Dipole the four electrodes move in relation to a center but at the same time they also move laterally whose objective is to see variations in resistivity in 2-D (X and Z).

 

Arrangements: Dipole-Dipole, Pole-Dipole, Pole-Pole, Wenner, Wenner-Schlumberger, Edge Gradient, Strong Gradient, among others.

 

Widely Applications: Environmental engineering, prospecting for mineral resources, geotechnics, geological characterization, civil protection for the determination of fractures, geological faults, detection of cavities and facies changes and archaeology.

 

Main Application

  • Mineral prospecting in geological surveys - identify potential mineral deposits.
  • Groundwater exploration - locate and assess water resources.
  • Environmental investigations - identify contamination and remediation sites.
  • Engineering projects - determine foundation stability and soil mechanics.
  • Archaeological studies - detect buried structures and artifacts.
  • Civil engineering - determine soil composition and geotechnical properties.
