Abstract
An electrical resistance corrosion probe incorporates a temperature sensitive resistor (RTD) that directly measures temperature of the probe and therefore of its environment as corrosion measurements are being made. The temperature sensitive resistor has one end connected to the common junction between the test and reference elements of the corrosion probe and has its other end connected in the common line to the several corrosion measuring circuits, including the test, reference and check circuits.
