<p>A contaminant detector disposed within a base fluid for detecting the presence of a contaminating fluid includes a conductive core, a conductive sensor probe extending from the core in non-conductive relation, and a circuit board within the core. The circuit board is electrically connected to the sensor probe and electrically insulated from the core. Electrical power applied to the core creates a closed field loop for measuring the localized capacitance of the base fluid. When sufficient contaminating fluid exists in the base fluid to change the localized capacitance, an alarm is sounded to indicate the presence of the contaminating fluid.</p>
