System composition
Multiplex Electrode Resistivity Meter Geophysical Equipment Resistivity Imaging ERT Electric Resistivity Tomograph for Underground Water Finder
One DZD-6A multi-functional DC resistivity instrument as the survey & control unit in the system, equipped with DUK-2A type 60 channels or 120 channels multiplex electrode converter, 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 English characters, more than fourteen types of wiring working modes can be directly displayed in high-density measurement mode; in DZD-6A stand-along mode, nine types of electrode arranging methods can be directly displayed; meanwhile, real-time curve display can be realized during working.
