Advanced Geophysical Exploration with WDJD-4A Multi-Function Digital DC Resistivity Meter
WDJD-4A represents the pinnacle of innovation in DC resistivity and induced polarization (IP) technology, engineered to deliver unmatched precision, versatility, and reliability for geological surveys. Built as an upgrade to the WDJD-3A, this instrument integrates cutting-edge hardware and intelligent software to address complex challenges in mineral exploration, groundwater detection, and infrastructure assessment.
Superior Measurement Accuracy
WDJD-4A achieves ±0.4% voltage precision and 24-bit A/D resolution, enabling the detection of microvolt-level electrical signals. This ensures high-fidelity data for identifying subtle subsurface anomalies, such as deep-seated mineral deposits or groundwater reservoirs.
Enhanced Anti-Interference Capability
Equipped with ≥80dB noise suppression against 50Hz industrial frequencies, the system maintains stable performance in high-electromagnetic environments (e.g., near power lines or urban infrastructure).
Multi-Mode Operation
Supports Resistivity (Res), IP, and hybrid Res/IP workflows, including:
Time-Domain IP for mineral discrimination
Multi-Electrode Resistivity Imaging for 2D/3D subsurface mapping
Spectral IP for advanced chargeability analysis
High-Power Transmitter
Delivers up to 6,600W output power (general Res/IP mode) and ±1,100V supply voltage, enabling deep penetration (1,000+ meters) for large-scale surveys.
Intuitive Data Management
Features 1GB onboard storage and USB 3.0/Wi-Fi connectivity for seamless data transfer. Integrated software enables real-time imaging, depth inversion, and 3D visualization.
