Digital Georesistivimeter for Vertical Electric Surveys. Equipment is characterized by maximum resolution and accuracy in geoelectric survey and great functioning rapidity. Once data acquisition is completed, data can be immediately processed with related data processing software. Power is supplied by embedded battery pack and it is managed through a microprocessor able to provide wide autonomy of acquisition. Recording and saving of data takes place on internal Disk or on USB key (supplied). Unit is fully computerized and all operating functions are selected simply by touching menu on transflective color LCD monitor 7 ' with integrated touch screen.
