INRiM – Istituto Nazionale di Ricerca Metrologica – is developing an experimental set-up for electrical resistance tomography (ERT). The system, placed in an electromagnetic shielded environment at constant temperature, performs series of four-terminal trans-resistance measurements in different contact configurations by means of a current source, a voltmeter and a reed-relay switch unit.
