Electrical Resistivity Tomography (ERT)

The Resistivity technique is a useful method for characterising the sub-surface materials in terms of their electrical properties. Variations in electrical resistivity (or conductivity) typically correlate with variations in lithology, water saturation, fluid conductivity, porosity and permeability, which may be used to map stratigraphic units, geological structure, sinkholes, fractures and groundwater. In the field of cultural heritage ERT is useful to detect archaeological structures.

Fields of application

  • Cultural heritage

    archaeological object and site

  • Natural heritage



  • inorganic



Syscal Pro resistivity meter

The Syscal Pro resistivity meter connected to the Syscal Switch Pro 96 can be used to capture and store the ERT field data. The instrument has the capability to simultaneously drive up to 96 electrodes which are laid out along a line which are connected to the resistivity unit through a multiclone cable.
