Geological investigation Equipment , Geophysical Exploration 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.
• 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

• 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.
