Corrosion Sensor: 8,833,146


A corrosion sensor may include a sensor body, a chloride probe held in the sensor body, a pH probe held in the sensor body, a reference electrode for the chloride probe and the pH probe held in the sensor body, a multiple array sensor held in the sensor body and a resistivity probe held in the sensor body. A method of measuring corrosion in a reinforced concrete structure may include inserting a corrosion sensor into a reinforced concrete structure and monitoring chloride ions with the chloride probe, pH with the pH probe, localized concrete resistivity with the resistivity probe and corrosion current density with the multiple array sensor.
