DZD-8 Geophysical Instruments for Groundwater Investigations (3)




The geophysical instruments is Widely used in the exploration of metal and non-metal mineral resources, groundwater resources / geothermal resources and other fields; it can also be used in the engineering geological investigation of dam foundation, hidden danger location of levee, bridge and tunnel investigation of highway / railway and urban geophysical exploration.


The geophysical instruments with Multi function: cover all functions of conventional resistivity / IP meter, 2D / 3D ERT system, rock sample tester and multi parameter water detector. 


The geophysical instrument can measure  multi parameters : voltage, current, apparent resistivity, apparent polarizability, natural potential, self electric gradient, half decay, attenuation, excitation ratio, deviation, metal factor, ground resistance and voltage decay curve (i.e. IP spectrum data).
