A leak detector that detects a potential fluid leak within an information handling system includes a signal generator, voltage divider circuitry, microstrip differential sensing element, signal processor, and fluid leak indicator. The signal generator generates an AC signal and conveys the AC signal to the microstrip differential sensing element through the voltage divider circuitry. The microstrip differential sensing element includes a pair of protectively covered, edge-coupled microstrip traces that, when driven by the AC signal, generate a sensing signal that is output to the signal processor. The signal processor determines a phase of the sensing signal and generates, based on the phase, a capacitance value associated with the microstrip differential sensing element. The fluid leak indicator indicates the occurrence of a potential fluid leak within the information handling system if the capacitance value exceeds a predetermined threshold.
