Digital High Accuracy Deep Earth Metal Detector

Applications:

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

Main Features:

Small,light,this 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: 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.
