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.

More flexible and convenient operating mode: Adopt all-digital 

automatic measurement, can execute automatic compensation for 

spontaneous potential, drift and electrode polarization. Use large 

screen LCD display, can directly display the arrangement of nine 

electrodes; directly input into pole arranging parameters with 

keyboard; measuring resistivity curve apparent polarizability curve, 

half-decay curve, etc. can be displayed directly when measurement of 

measuring point completes,

Data Interpretation is more convenient: The instrument can measure 

points on 4,800 survey data for storage. Each measuring point has 22 

data, with RS-232 serial interface, through appropriate software the 

stored data can be directly transfer to the computer for digital 

interpretation of various methods.

Beautiful Instrument Apparent, Strong Structured: The aluminum chassis 

effectively enhance the electromagnetic shielding; adopts thin-film 

multi-layer sealed touch panel; multiple over-voltage, over-current 

automatic protection are set for internal power supply part, allowing 

the instrument to be suitable for various types of field environment.
