Vertical Electrical Resistivity Meter Digital Geophysical For Underground Water Detector

The WDDS-2C/3C digital resistivity meter, developed by GOLD, is a highly advanced DC resistivity equipment that features state-of-the-art technology. It incorporates 32-bit microcontroller technology and 24-bit A/D technology, positioning it as a cutting-edge solution for conducting accurate and reliable resistivity surveys. This versatile instrument finds applications in diverse fields such as mineral resource detection, geophysical exploration in urban areas, railway and bridge inspections, hydrology, engineering geology, and geothermal prospecting. 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.

Main Features

Bluetooth technology and wireless remote control: Control the WDA-1/WDA-1B mainframe up to 10 meters away using Bluetooth, simplifying tasks such as parameter setting, measurements, result display, and data storage.
Tablet PC operation with powerful functions: Perform all activities on a tablet PC, including parameter setting, data display, storage, and curve drawing, streamlining data processing.
Grounding resistance check: Determine the ground condition of each electrode for accurate assessments.
Fault diagnoses: Instantly detect faults and locate damaged parts for efficient troubleshooting.
Sealed configuration: Waterproof, dust-proof design with a long lifespan.
Light and flexible: Compact transmitter and receiver unit with a built-in high-voltage power supply (only WDDS-3C), eliminating the need for additional bulky battery boxes.
Large power supply, wide range, high precision: 6000W power supply capacity, 100Vp-p wide voltage input range, and high accuracy measurement of small signals for effective performance in high resistance areas and obtaining accurate measurement results at greater depths.
