The ac-SECM is a new technique that has the capability to measure surface phenomena without the presence of a mediator. This feature allows the SECM technique to be used in the field of corrosion science.
The SECM technique can be combined with the OSP470 module or the ic-SECM470 module to allow the technique to make both constant height and constant distance measurements.
