Geophysical Surveys Electrical Resistivity Induced Polarization Meter Subsurface Water Detection Instrument Geo VES Mineral Deposits Equipment
The Electrical Resistivity Induced Polarization (IP) meter is a geophysical instrument that measures the electrical properties of the subsurface. It provides valuable information about the resistivity and polarization characteristics of the rocks and soil layers, aiding in the identification of subsurface features, geological structures, and potential mineral deposits. The IP meter uses electrical currents and voltage measurements to assess variations in subsurface resistivity, which can indicate the presence of different geological formations and mineralization.
Main Applications
By utilizing relevant parameters of apparent resistivity and induced polarization method, the instrument is widely used in many aspects including metal and non-metal mineral resources exploration, energy exploration, city geophysical exploration, railway and bridge engineering exploration, etc.
Search for groundwater, solve the human and animal drinking water issue as well as industrial and agricultural water issue. Determine the hidden safety risk location in reservoir dam foundation and flood-control dyke, find faultage zone and collapse column, landslides, coal mining goaf, search for geothermal and other hydrological, engineering geological exploration.
Accessories made by our factory with 60-channel or 120-channel multiplex electrode switch, also can be used for multi-electrode resistivity survey system.
Main Features:
Multiple functions in One Machine: The instrument has three functions including long lead IP instrument, master of 2D resistivity imaging system, and medium-power short lead transmitting.
Small-sized, Light in weight: The instrument integrates receiver and transmitter together in the same cabinet, which can be used for measurement via apparent resistivity method and induced polarization method.
Various Measurement Parameters: Instrument can be applied in direct measurement and indication of primary potential Vp, spontaneous potential Vsp, power supply current I, apparent resistivity Ro, apparent polarizability Ms, half-decay time Th, degree of decay D, integrated IP parameters Zp, and degree of deviation R.

Dc resistivity method is widely used to find the mine water-bearing abnormal body. The three-dimensional electrical method based on the two-dimensional graph can visually show the three-dimensional geometric model, and the pseudo-three-dimensional high-density electrical method can be used to detect the three-dimensional geological model. According to the continuity of geological structure between the two-dimensional planes, the measured data can be combined into a three-dimensional geological model. A relatively accurate bipolar detection device was selected, and the WGMD high-density electrical method system was adopted. The smooth constrained least squares inversion method was used to process the detection data repeatedly and iteratively, and the static correction technology was integrated to modify the detection data, so as to visualized Slicer in three dimensions The Dicer system obtains the slice data volume, delineates the approximate range of the abnormal low resistance body, and ensures the accurate judgment of the mine water cut abnormal body.
