The WDDS-2C digital resistivity meter allows you to:
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.
