Product Description

Geophysical Equipment Underground Water Detector 2D Tomograph Resistivity Equipment Multi Electrode Resistivity Surveying System

WDJD-4 Multi-function Digital DC Resistivity/IP equipment is the updated model of WDJD-3 multi-function digital DC Res/IP terrameter, which install a 12V rechargeable battery.It features multiple functions, high accuracy, fast speed, high reliability and excellent expandability.Measured data of WDJD-4 equipment can be processed by other multi-electrode resistivity software, which makes the interpretation more convenient.

Application:
•  Metal and nonmetal mineral resources detection
•  City geophysical exploration, railway and bridge inspection
•  Hydrology and engineering geology as seeking for ground water, inspecting dam base and flood protection levee for incipient faults
•  Geothermal prospecting

Function:
•  1D resistivity sounding
•  1D induced polarization sounding
•  2D Resistivity imaging
