A sensor for an electrochemically active species, such as oxygen, uses more than two electrodes, namely, at least a working electrode, counter electrode and reference electrode. The sensor preferably is substantially planar, is made using thick film or thin film technique and accordingly may be very small. With the sensor in an electrolyte balanced reverse reactions occur, respectively, at the working and counter electrodes while no reaction occurs at the reference electrode, which is maintained in equilibrium with the electrolyte, and voltage between the working the reference electrodes is maintained constant. Current flow between the working and counter electrodes, then, provides an accurate, stable representation of species concentration.
