System Composition
One DSHZ-6A
multi-functional DC resistivity instrument as the survey and control unit in
the system, equipped with a DSHK-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.
