Product Description
Non-Metal Detector
Multi-Electrode Resistivity survey
1.Main
Applications
-
Widely used
for high-resolution research, tomography and monitoring
applications.
-
Coal mining
gobs, caves of Custer area, geological disasters survey like landslides other
geological disasters.
-
High
resolution engineering geological exploration like factory foundations,
highways, bridges, railways, civil engineering, hydrology, engineering,
environmental.
-
For
landslides and other geological disaster exploration.

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.
