Electrical Underground DC Resistivity and IP Instrument

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, search for geothermal and other hydrological, engineering geological exploration.
With 60-channel & 120-channel multiplex electrode switch made by our factory, this instrument can also be used as multi-electrode resistivity survey system.

Main features
Small,light,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 Parameter: 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.
