DUK-2A Geophysical Instrument Multi-Electrode Resistivity Survey System

Geological Survey, Underground Water Detector, Ground Water Finder, Geophysical Instrument, Geophysical Equipment, Multi-Electrode Resistivity Survey Syste

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.
Metal and non-metallic mineral resources exploration and geothermal exploration

Main Features.
Assembly data acquisition devices and multiplexer together in the same case,which not only reduce the volume but also decrease the weight, thus avoid errors caused by operating the devices separately and due to inconformity of switch parameter settings.
Maintain all functions of DUK-2A Multi-Electrodes Resistivity Survey System and conventional electrical method.
Add high and low current transform taps, add high and low input impedance transformation tap, and improve the acquisition capability of weak signals.
Add storage and output functions for compensation SP voltage value.
Adopt 16-bit A/D and 16-bit D/A, thus improve the discernibility for measurement of collected data.
Add the function for automatically detect grounding resistance before each measurement; give directions for the points exceed the grounding resistance value, for automatically proceeding with further measurement if required; the value at such point can be replaced with a fixed symbol to facilitate the elimination of this point while processing the information and data.
Greatly enhance the repeatability of measured data.
