WGMD-4 Electrical Resistivity Tomography System: Precision Redefined for Subsurface Exploration
Introduction
The WGMD-4 Electrical Resistivity Tomography (ERT) System is a state-of-the-art geophysical instrument engineered to deliver high-resolution imaging of underground structures across diverse applications, including groundwater detection, mineral exploration, and infrastructure safety assessments. Designed for professionals in geology, civil engineering, and environmental science, this system combines advanced technology with user-friendly operation to revolutionize subsurface analysis.
Key Features
Multi-Electrode Array Flexibility: Supports 12+ configurations such as Wenner, Schlumberger, Dipole-Dipole, and Cross-Hole Dipole, enabling tailored surveys for varying geological conditions.
High-Precision Data Acquisition: Achieves ±1% apparent resistivity accuracy and ±5‰ current measurement precision, ensuring reliable detection of underground anomalies like caves, sinkholes, and mineral deposits.
Robust Anti-Interference Design: Features ≥80dB noise suppression to maintain stability in high-interference environments, such as near industrial zones or urban infrastructure.
