WDJD-4A: The Gold Standard in Geophysical Survey Technology
Engineered for professionals demanding uncompromised performance and adaptability, the WDJD-4A Multi-Function Digital DC Resistivity Meter redefines efficiency in subsurface exploration. Combining military-grade durability with AI-driven analytics, this system empowers geoscientists to tackle projects ranging from deep mineral prospecting to urban infrastructure diagnostics with unprecedented confidence.
Unrivaled Signal Sensitivity
Detect anomalies at unprecedented depths using 24-bit A/D converters and 0.1µV voltage resolution, enabling identification of micro-fractures, mineralized zones, and aquifer boundaries missed by conventional tools.
Intelligent Noise Cancellation
≥80dB suppression against 50Hz interference ensures clean data acquisition in urban, industrial, or mountainous terrains-ideal for near-surface utility mapping or deep geothermal surveys.
Modular Workflow Flexibility
Seamlessly transition between Resistivity, IP, and hybrid modes, including:
High-Density Resistivity Imaging: Achieve 5x faster data collection with multi-electrode configurations.
Time-Domain IP Profiling: Discriminate between sulfide ores and waste rock using decay curve analysis.
Spectral IP Mapping: Quantify chargeability variations for hydrocarbon reservoir characterization.
Powerhouse Transmission
6,600W maximum output and ±6A current delivery penetrate 1,200+ meters through dense basalt or glacial till, outperforming legacy systems like WDJD-3A by 300% in depth capability.
Cloud-Ready Data Integration
1GB onboard storage paired with Bluetooth 5.0 enables real-time data streaming to tablets or cloud platforms for AI-powered geological modeling and collaborative interpretation.
