Product Description

2D 3D Multi-Channel Geo Electrical Resistivity Imaging Tomography Equipment for Underground Exploration Mining and Groundwater

Product Description

WGMD-9 super digital DC resistivity/IP meter is a newly developed electrical method instrument, adopting many advanced technologies such as pocket PC, Bluetooth, 24bit A/D, and high power control. It features compact size and lightweight. Its main performance and functions are better than its similar products at home and abroad.

2D multi-electrode resistivity method belongs to DC resistivity method substantially, it's using the same fundamental with DC resistivity method but different combined section appliance. This system supports 16 types of measuring appliance, including wenner array (α), dipole array (β), differential array (γ), combined section array A (δA), combined section array B (δB), AM array, AMN array, ABM array, ABMN array, MNB array, Schlumberger array (α2), SP M, SP MN, Charging M, Charging MN array and Across-dipole array.
