Introducing the WDJD-4A Multi-Function Digital DC Resistivity Meter: Precision Redefined for Modern Geophysical Exploration
The WDJD-4A Multi-Function Digital DC Resistivity Meter represents a groundbreaking advancement in geophysical survey technology, engineered to deliver unparalleled accuracy and versatility across diverse exploration scenarios. Built upon the robust foundation of its predecessor, the WDJD-3A, this next-generation instrument integrates cutting-edge hardware and intelligent software solutions to address the evolving demands of mineral exploration, hydrological studies, and engineering geology.
Superior Measurement Accuracy
The WDJD-4A achieves ±0.4% voltage precision and 24-bit A/D resolution, enabling the detection of minute electrical resistivity variations in subsurface structures. This precision is critical for identifying deep-seated mineral deposits, mapping groundwater reservoirs, and assessing geological hazards with unmatched reliability. For instance, its ability to resolve signals as low as 0.1 microvolts ensures accurate delineation of ore boundaries even in complex terrains.
Enhanced Anti-Interference Capabilities
Engineered with advanced noise suppression technology, the WDJD-4A achieves ≥80dB rejection of 50Hz industrial interference, making it ideal for surveys near power lines or urban infrastructure. This ensures stable data acquisition in electromagnetically noisy environments, a common challenge in modern geophysical applications.
Multi-Mode Operational Flexibility
The system supports Resistivity (Res) and Induced Polarization (IP) measurements, alongside specialized modes like multi-electrode imaging, time-domain IP, and spectral IP. This adaptability allows users to tailor surveys for specific objectives, whether prospecting for metals, evaluating dam integrity, or geothermal resource assessment.
High-Power Transmitter for Deep Exploration
With a maximum output of 6600W and ±6A current capacity, the WDJD-4A penetrates deeper geological layers compared to conventional systems. This capability is indispensable for large-scale mineral exploration or mapping deep aquifers, where signal strength directly correlates with data quality.
User-Centric Design & Efficiency
Featuring a 160×160 dot-matrix LCD and intuitive touchscreen interface, the WDJD-4A simplifies field operations. Its 12V rechargeable battery provides 30 hours of continuous use, while 1GB storage capacity and USB 3.0/Wi-Fi data transfer streamline workflow integration.
