Main Applications:

1. Widely used for high-resolution research, tomography and monitoring 

applications.

2. Coal mining gobs, caves of Custer area, geological disasters survey 

like landslides other geological disasters.

3. High resolution engineering geological exploration like factory 

foundations, highways, bridges, railways, civil engineering, 

hydrology, engineering, environmental.

4. For landslides and other geological disaster exploration.
Metal and non-metallic mineral resources exploration and geothermal 

exploration.

System Composition: 

One DAZ-6A multi-functional DC resistivity instrument as the survey 

and control unit in the system, equipped with a DUK-2A type 60-channel 

or 120-channel multiplex electrode switch manufactured by our factory, 

and cables, electrodes and other related accessories, together to form 

the resistivity imaging system. 

Main Features:

Multiple function in one machine: The instrument has four functions 

including long lead IP instrument, 2D high density resistivity meter, 

2D high-density IP instrument, and medium-power short lead 

transmitter.

Easy for Operation: The instrument adopts all-digital automatic 

measurement, thus can execute automatic compensation for spontaneous 

potential, drift and electrode polarization. By adopting large screen 

LCD display in Chinese characters, more than fourteen types of wiring 

working mode can be directly displayed in high-density measurement 

mode; in DZD-6A stand-alone mode, nine types of electrode arranging 

methods can be directly displayed; meanwhile, real-time curve display 

can be realized during working.

Extra-large Storage: In high-density mode, the instrument can store 

the measured data at 120,000 measuring points; in DZD-6A stand-alone 

mode, the instrument can store the measured data at 4,800 measuring 

points; there are 22 digits at each measuring points, provided with 

RS-232 serial interface, and the stored data can be directly 

transferred to the computer by means of appropriate software to carry 

out digital interpretation for various methods.
