Products Description
The RCWD-9 is a complete groundwater resistivity meter system consisting of the WDA-1 Digital DC Resistivity Meter, WDZJ-120 Multi-Electrode Switcher, and PDN-500 Portable Inverter Power Supply.
The system uses electrical resistivity tomography (ERT) to collect resistivity data from multiple electrode combinations. Differences in subsurface electrical resistivity can be used to identify geological boundaries and potential water-bearing zones. Survey data can be visualized as resistivity profiles on the tablet, providing a practical reference for groundwater drilling and geological investigation.
The system is supplied with 32-core high-density survey cables, copper electrodes, cable reels, AB power cables, and other field accessories. Its split configuration makes transportation and deployment more convenient, particularly for rural, mountainous, and confined survey locations.

Products Features
Competitive advantage
The company conducted a competitive advantage analysis to identify its strengths and weaknesses compared to its rivals.
High-Resolution Groundwater Investigation
The Resistivity Meter for Groundwater Exploration detects subsurface resistivity variations to help identify potential aquifers, fractured water-bearing zones, and relatively impermeable formations.
01
Lightweight Split Configuration
The main components can be transported separately, making the system easier to carry and deploy in mountainous areas, farmland, villages, and locations with limited vehicle access.
02
Wireless Tablet Operation
The system can be operated through a wireless tablet connection, allowing convenient field control and data acquisition without long cables between the operator and instrument.
03
Flexible Electrode Spacing
Multiple electrode spacing configurations can be selected according to survey requirements, covering relatively shallow groundwater investigation as well as deeper geological and geothermal surveys.
04
On-Site Resistivity Imaging
Collected data can be processed and displayed as underground resistivity profiles in the field, helping users quickly assess possible water-bearing structures and geological anomalies.
05
