Product Description

Wenner Array Geophysical Exploration Instrument for Hydrological Investigation

 

 

Introduction

 

Geophysical surveys are an extremely useful geophysical method for studying the ground conditions to a significant depth and over a large area. Geophysical survey is utilised in many applications for subsurface investigations, mineral exploration being one of them.

 

Geophysical surveys is popular for Hydrogical Investigation, to study underground water and boreholes. There are various type geophysical equipment for this use. Such as China WGMD multi electrode resistivity imaging system.

 

Electrode arrays of multi-electrode system:

 

multi-electrode imaging,

Wenner Alpha array (WENNERα)

Wenner Beta array (WENNERβ)

Wenner Gamma array (WENNERγ)

Three-pole direct array (δA ARRAY)

Three-pole reverse array (δB ARRAY)

Wenner Alpha 2 array (SCHLMBG)

Self-Potential M array (SP-M)

Self-Potential MN array (SP-MN),

Charging M (CHG-M)

Charging MN (CHG-MN),

Two-pole Roll along array (2P AM),

Three-pole Roll along array (3P A-MN and 3P AB-M),

Dipole-dipole Roll along array (DIPOLE),

Cross-Hole Dipole/Equatorial Dipole-dipole array (CR-DIPOLE).
