2D Geological Mapping and Electrical Resistivity Tomography (ERT) Survey Instrument Geophysical Resistivity Equipment for Groundwater, Metal, Mineral Detection
Product Description
Electrical Resistivity Tomography (ERT) is a geophysical method widely used for subsurface investigation, mapping the variation in electrical resistivity of materials beneath the Earth's surface. This technique provides valuable information for a range of applications, from environmental studies to engineering and construction projects. The primary tool for conducting ERI surveys is the specialized ERI equipment, which uses electrical currents to measure resistivity across different layers of the ground. In this article, we will explore the key features, advantages, and common use cases of Electrical Resistivity Imaging Equipment

Key Features of 2D Geological Mapping and Electrical Resistivity Tomography (ERT) Survey Instrument Geophysical Resistivity Equipment for Groundwater, Metal, Mineral Detection
Multiple Electrode Configuration:
Electrical resistivity tomography equipment consist of multiple electrodes placed along a survey line or grid. These electrodes are used to inject electrical current into the ground and measure the potential difference. The number and spacing of electrodes can be adjusted depending on the resolution and depth of investigation required.
Data Acquisition and Processing:
The equipment measures the resistance (or resistivity) of different subsurface materials by passing a current through the electrodes. The data is then processed through specialized software that generates 2D or 3D images of subsurface resistivity distribution. This allows for a detailed analysis of geological formations, groundwater flow, and contamination.
High Sensitivity and Resolution:
ERT survey systems can achieve high spatial resolution, enabling the detection of small-scale heterogeneities in the subsurface. The equipment is sensitive enough to measure resistivity variations in various materials, including rocks, soils, and groundwater.
Portability and Field Use:
Electrical resistivity tomography equipment is designed to be portable and rugged, suitable for use in various field conditions, from urban environments to remote locations. Modern systems often feature compact units, with wireless capabilities for easy data transfer, and long-lasting batteries to support extended field operations.
Adjustable Measurement Parameters:
Operators can adjust measurement parameters such as electrode spacing, current intensity, and measurement frequency to optimize data acquisition for specific survey objectives. This flexibility makes ERT equipment highly adaptable to different geological conditions and survey scales.
