Abstract
This study deals with the use of a non-invasive measuring system, the presence of moisture inside objects of interest for the cultural heritage. The study has principally focused on certain types of stones, however, this analytical method can be employed in many other fields, such as the building sector in general.
A method based on Direct Current Resistivity (DCR: Direct Current Resistivity) measurement through four aligned electrodes on the sample surfaces is proposed to obtain a wetlands mapping at various depths of investigation. To achieve this purpose have been built several electrodes contact devices in conformity with the Wenner array and optimized for their reliably and nondestructive application on rigid surfaces.
