Digital Geophysical Underground DC Resistivity And IP Instrument

Digital Geophysical Underground DC Resistivity And IP Instrument

Small,light,this underground metal detector 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: underground metal detector 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.

By utilizing relevant parameters of apparent resistivity and induced polarization method,this underground metal detector 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 underground metal detector can also be used as multi-electrode resistivity survey system.
