Scanning systems

The Model SKP470 Scanning Kelvin Probe operates using a vibrating capacitance probe and through a swept backing potential, the work function difference is measured between the scanned probe reference tip and sample surface.

This enables the user to map and quantify localised electrochemical and corrosion events in real time.

The probe vibration is controlled by a piezo-ceramic displacement device allowing vibration amplitudes from 1 – 30 μm (perpendicular to the sample surface).
