Electrochemical noise module

Electrochemical noise module
Order number: ECN

Electrochemical noise (ECN) is an in-situ technique for measuring these localized corrosion processes on bare or coated metal samples. During measurements with the ECN module no external perturbation (potential or current) is applied to the electrode. The potential and current signals are measured as a function of time.

The accompanying analysis software allows the current and potential versus time data to be analyzed using Fast Fourier Transform (FFT). The software also provides several filtering and mathematical methods for treating electrochemical noise signals.
