It offers exceptional capabilities for precise detection of both metallic and non-metallic resources, groundwater exploration, identification of faults in dam bases and flood protection levees, and various other geophysical investigations.
WHAT CAN I DO WITH IT?
The WDDS-2C digital resistivity meter allows you to:
- Conduct mineral resource detection
- Perform geophysical exploration in urban areas
- Inspect railways and bridges
- Study hydrology and groundwater exploration
- Conduct engineering geology assessments
- Explore geothermal prospects
- Identify faults in dam bases and flood protection levees
WHAT IS ITS PRINCIPLE?
The WDDS-2C digital resistivity meter operates based on the principle of electrical resistivity measurement. It utilizes the concept that different materials and subsurface structures exhibit varying electrical resistivity characteristics. By injecting a controlled electrical current into the ground through electrodes and measuring the resulting potential differences, the instrument can determine the resistivity distribution of the subsurface.
