High Speed ER (Microcor®)

The Microcor® corrosion monitoring technology has been developed to substantially increase the speed of response over conventional corrosion monitoring techniques, such as coupons, electrical resistance (ER) probes, and linear polarization resistance (LPR), and is functional in all environments. Microcor® high speed corrosion monitoring is the result of patented technology which combines the rapid response of LPR and the universal applicability of ER. The figure below compares the real world response of various internal corrosion monitoring methods to the Microcor® system. Corrosion rate on a logarithmic scale is plotted against time, also on a logarithmic scale. At 10 mpy, the common W40 electrical resistance probe takes nearly 3 days to show a clear response. A Microcor® internal corrosion monitoring probe with the same useful probe life will show a clear response in 1 hour, and the trend is visible in 15 minutes. Even an LPR corrosion monitoring probe in water will take 5 to 10 minutes to produce a steady corrosion rate reading. This means that the Microcor® corrosion monitoring system is 50 to 100 times more sensitive and faster in response than ER systems. The absolute resolution of the Microcor® electronics is 256 times more sensitive than ER system electronics.
