A fluid sensor for a downhole tool positionable in a wellbore penetrating a subterranean formation. The downhole tool has a housing with a flowline therethrough receiving a downhole fluid therein. The fluid sensor includes an insulative base positionable in the downhole tool, a conductive shield positionable on the insulative base, and a plurality of electrodes each having a non-conductive coating thereon. Each of the electrodes includes a sensing element and a pin. The sensing element is positionable in the insulative base and exposed to the downhole fluid passing through the flowline. The pin operatively connects the sensing element to a downhole unit whereby parameters of the downhole fluid are measured.
