Corrosion related electrochemical noise

Noise Probe

Noise Probe
The Noise Probe is a low power potentiostat for the ZENNIUM-series potentiostats and is specially designed for all common electrochemical noise techniques. In addition Zahner developed CorrElNoise®. This revolutionary new method is superior to common ECN techniques as it measures the current and voltage noise in (quasi-)parallel condition by fast switching between the open circuit potential and short circuit conditions.

The Noise Probe can carry out different kind of measurements which are listed below.
  • Open circuit potential noise (OCPN)
  • Potentiostatic controlled current noise (PCCN)
  • Galvanostatic controlled potential noise (GCPN)
  • Uncorrelated current & potential noise (UCPN)
  • Correlated electrochemical noise (CorrElNoise®)
