Groundwater Survey Equipment Resistivity Imaging Technology Geophysical Resistivity Meter

Groundwater Survey Equipment Resistivity Imaging Technology


The Geophysical Resistivity Meter is a state-of-the-art instrument designed for comprehensive subsurface exploration. It integrates advanced resistivity and IP imaging technologies, making it indispensable for a wide range of applications.


Key Features:


  • Multi-functionality: Capable of 2D and 3D resistivity imaging, IP measurements, and groundwater detection.

  • High precision: Measures voltages as low as 0.1mV and currents as small as 0.1mA with ±1% accuracy.

  • Wireless control: Operates via Bluetooth-enabled Pocket PC, allowing remote control within a 10-meter range.

  • Robust design: Encased in an imported airproof box, it is waterproof, dustproof, and built for durability.


Applications:


  • Energy exploration: Ideal for locating oil, gas, and geothermal resources.

  • Civil engineering: Essential for surveying dam sites, bridges, and railways.

  • Mineral exploration: Effective in detecting both metallic and non-metallic minerals.

  • Hydrogeology: Used for groundwater detection and flood risk assessment.


Advantages:


  • Portability: Combines transmitter and receiver in a compact, lightweight unit.

  • Wide measurement range: Supports voltage, current, apparent resistivity, SP, and IP parameters.

  • Anti-interference technology: Utilizes multi-stage filtering and signal enhancement for high accuracy.

  • User-friendly interface: Pocket PC control simplifies data sampling, storage, and analysis.
