How a Kelvin Probe Works by KP Technology
KP Technology's Prof. Iain D. Baikie explains how a Kelvin Probe works.
He explains the null field phenomena that was suggested by Lord Kelvin and then goes on to explain how he modified the technique to create the off null technique which overcomes the noise problems associated with the null technique, making it a useful tool for materials analysis.
