Product Description

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

1. Introduction to Cutting-Edge Resistivity and IP Technology

The WDA-1/WDA-1A Super Digital DC Resistivity/IP Meter represents a paradigm shift in geophysical exploration, integrating 24-bit A/D conversion, Bluetooth-enabled remote control, and dual power supply modes (external DC/internal HV). Designed for high-accuracy subsurface imaging, this system outperforms conventional instruments with:

• 7200W maximum power output (1200V×6A) for deep-penetration surveys.

• 0.1mV voltage precision (±1% accuracy) in harsh environments.

• 16+ electrode array configurations, including Wenner, Schlumberger, and dipole-dipole for versatile field applications.

Key Innovations:

• Portable yet powerful: Combines lightweight design (≤4kg) with industrial-grade durability (IP67-rated).

• Real-time data visualization: Compatible with PDA/notebook control via Bluetooth (10m range).

 

2. Unmatched Technical Specifications

Core Performance Metrics (Table 1):

Parameter	WDA-1/WDA-1A Specification	Industry Standard
Transmitting Power	7200W (1200V×6A)	Typically ≤5000W
Voltage Accuracy	±0.2% (Vp≥5mV), ±1% (0.1mV≤Vp<5mV)	±2.5% for most competitors
Current Range	0.1mA-6A (±0.2% accuracy)	Limited to 3A in similar units
SP Compensation	±10V range	±5V common in other devices
Operating Temperature	-10°C to +50°C (95% RH)	-5°C to +45°C for peers

Why This Matters:

• Higher power-to-weight ratio enables surveys in high-resistivity terrains (e.g., bedrock or arid regions).

• Superior signal-to-noise ratio due to 80dB+ 50Hz interference suppression.

 

3. Multi-Electrode Imaging Capabilities

The system supports 2D/3D resistivity and IP imaging via two workflows:

Option 1: WDZJ-3 Multiplex Electrode Converter

• 60-electrode capacity (expandable via cascading).

• 450V/2.5A limits, ideal for shallow-to-mid-depth surveys.

Option 2: Intelligent 10-Take-Out Cables

• 800V/3A tolerance for deep-sounding applications.

• Cross-hole dipole arrays via dual Socket 1+2 connectivity.

Field-Proven Advantages:

• Automated roll-along scanning reduces setup time by 40% compared to manual systems.

• Earth resistance monitoring alerts users to poor electrode contacts (<5kΩ threshold).

 

4. Applications Across Industries

4.1 Mineral Exploration

• Detect sulfide deposits using IP chargeability (M1-M7) with ±1% polarizability accuracy.

4.2 Groundwater Assessment

• Quadratic time difference (DT2) mode identifies aquifers by analyzing decay time differentials between high/low-voltage pulses.

4.3 Civil Engineering

• Dam/levee integrity checks via high-density 3D imaging (5m electrode spacing recommended).

 

5. Compliance and Durability

• Meets IP67 standards for dust/water resistance.

• Lithium battery safety: Auto-cutoff at 6.6V to prevent damage.

Maintenance Tips:

• Recharge every 3 months during storage (0°C-45°C).

• Replace 2A fuse in WDA-1A if internal HV shorts occur.
