Product Description

Advanced Geophysical Survey Solutions: WDA-1/WDA-1A Super Digital DC Resistivity/IP Meter

The WDA-1/WDA-1A Super Digital DC Resistivity/IP Meter is a cutting-edge geophysical instrument designed for high-precision subsurface exploration, combining 24-bit A/D conversion, Bluetooth wireless control, and multi-electrode imaging capabilities. Engineered for professionals in mineral prospecting, hydrology, and civil engineering, this system delivers unparalleled accuracy in measuring apparent resistivity, induced polarization (IP), and self-potential (SP).

Key Selling Points

1. High-Power Output & Precision:

   • 7200W maximum transmitting power ensures reliable performance in high-resistivity environments.

   • Voltage measurement accuracy of ±0.2% and current accuracy of ±0.2% for datasets with minimal noise interference.

   • SP compensation range up to ±10V and 80dB industrial-frequency suppression eliminate environmental interference.

2. Multi-Electrode Flexibility:

   • Supports 16 electrode array configurations, including Wenner α/β/γ, Schlumberger, and dipole-dipole, adapting to diverse geological challenges.

   • Cross-hole dipole array compatibility simplifies complex 3D imaging without additional switching units.

3. Portability & Durability:

   • Compact design (270mm x 246mm x 123mm, ≤4kg) ideal for rugged fieldwork.

   • IP67-rated waterproof casing and -20°C to +60°C operational range ensure reliability in extreme conditions.

4. Smart Power Management:

   • Dual power options: internal 96V lithium battery or external DC high-voltage input.

   • Automatic battery protection prevents over-discharge, with a 20-hour continuous operation lifespan.
