China Underground Layers Scan Instrument 120 Channels Resistivity Tomograph Equipment 60 Channels Electrical Resistivity Imaging System

Underground Layers Scan Instrument 120 Channels Resistivity Tomograph Equipment 60 Channels Electrical Resistivity Imaging 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
