The scanning vibration reference electrode system of the electrochemical microscope uses vibrating electrodes and lock-in amplifiers to eliminate noise interference in micro area scanning and improve measurement accuracy. This system has high sensitivity and non-destructive characteristics, and can be used for measuring electrochemical activity. It can be used for linear or surface scanning, local corrosion research, surface coating and corrosion inhibitor evaluation, etc. Vibration probe is a powerful tool for corrosion research in liquid corrosive environments. It cannot detect in-situ corrosion of 5ua/cm2.

Electrochemical microscopy provides a new method for surface science measurement, which can be used to measure the work function difference between conductive, semiconducting, or coating materials and sample probes. This technology is suitable for vibration capacitance probes. By adjusting the applied voltage, the work function difference between the sample surface and the reference of the scanning probe can be measured. The improvement of the theory that the work function is directly related to surface conditions has made SKP a valuable tool. Its measurement capability in humid and even gaseous environments makes it possible to conduct real-world research that was previously impossible.
