ER PROBES

ER Probes are required when using MetriCorr ICL units in order to determine corrosion rates and measure electrical fingerprints.

The probe simulates a coating defect. Measuring the electrical resistance of the exposed coupon element and a shielded reference element yields the probe thickness by use of simple mathematical algorithms.

Simultaneous logging of corrosion rate and electrical fingerprints allows for effective analysis of e.g. interference conditions. Measurement of all parameters, (corrosion rate, AC/DC potentials, AC/DC current densities and spread resistance) on the same metal surface ensures that all interacting chemical and electrochemical reactions are part of the analysis.

ER probes can be used to analyze corrosion in a wide range of environments, and various probe designs and housing materials ensures that the probes are fit for purpose and will continue to provide valuable corrosion and CP information to the operator throughout its life-time.

The latest version of MetriCorr ERv2 probes have embedded memory in the plugs, containing a digital certificate. This will automatically be read by the Slimline ICL or ICL-C from MetriCorr upon connecting the probe and the units are ready to measure.
