The Kelvin Probe is a non-contact, non-destructive vibrating capacitor device used to measure the work function (wf) of conducting materials or surface potential (sp) of semiconductor or insulating surfaces. The Kelvin Probe does not actually touch the surface; rather an electrical contact is made to another part of the sample or sample holder.
We are proud distributors of the Kelvin Probe systems from KP Technology, one of the top developers of the Kelvin Probe Systems.
