A corrosion detection system, comprising: a chassis for a device; a memory configured to store reference data; a corrosion monitor comprising: a printed circuit board; a corrosion sensor coupled to the printed circuit board, the corrosion sensor comprising a first input and a second input, the corrosion sensor configured to output a signal proportional to a resistance of the chassis of the device; a first standoff coupled between the printed circuit board and the chassis of the device; a second standoff coupled between the printed circuit board and the chassis of the device; a third standoff coupled between the printed circuit board and the chassis of the device; a fourth standoff coupled between the printed circuit board and the chassis of the device; a constant current source coupled to the first standoff and configured to output a constant current to the chassis through the first standoff; a first trace coupled between the third standoff and the first input of the corrosion sensor; and a second trace coupled between the fourth standoff and the second input of the corrosion sensor, wherein the corrosion sensor is configured to output the signal proportional to the resistance of the chassis of the device based upon voltages induced by the constant current source through the first standoff at the first input and the second input; a processor communicatively coupled to the memory and the corrosion monitor, the processor configured to receive the signal proportional to the resistance of the chassis of the device from the corrosion monitor and determine a corrosion level of the chassis of the device by comparing the signal proportional to the resistance of the chassis from the corrosion monitor to the reference data stored in the memory, characterised in that the first standoff, the second standoff, the third standoff and the fourth standoff are separating the printed circuit board from the chassis, and in that the voltages at the first input and the second input are dependent on a resistance of the chassis between the first standoff and the third standoff, a resistance of the chassis between the first standoff and the fourth standoff and a resistance of the chassis between the second standoff and the fourth standoff. a chassis for a device;
