The EuropCorr® MaxiCorr meter is a handheld corrosion meter designed to measure corrosion rate in both conductive liquids as well as in non conductive media. The MaxiCorr meter incorporates two techniques "Electrical Resistance (ER) & Linear Polarization Resistance (LPR)"

OPERATING PRINCIPLE
ER measurement: relies on the direct measurement of the electrical resistance of a probe that employs a sensing element made of the same metal as the pipeline or structure monitored; the sensing element is produced with form of wire, strip or tube. The cross-sectional area of the sensing element decreases if corrosion occurs, and its electric resistance increases according to Ohm.
The MaxiCorr performs a convergent autorange algorithm that can find quickly the best scale of measure. A single MaxiCorr can be used to measure an unlimited number of probes installed at different locations of the system. Each Probe can be distinguished by a unique TAG number & alphanumeric 14 characters description and measures are memorised in a non-volatile memory. The MaxiCorr is simple to operate, set TAG number and push the Measure key, the instrument will give a corrosion rate reading and automatically memorises data; collect data from Field Unit's; upload settings to Field Unit's or upload data to Terminal PC acting as a portable data logger and Terminal.

LPR measurement: relies on the measurement of the electrical resistance of the corroding electrode-electrolyte interface. The polarization resistance is measured as the ratio of the applied DC potential to the flowing current and is constant over a small range (<20mV).
