A thick film electrochemical micro-sensor device for detecting or monitoring sulfur dioxide, comprising a substrate to which is applied a working electrode, a counter electrode, a reference electrode, and optionally a heater and a temperature detector, wherein a portion of the electrodes is covered with an insulator, and a portion of the electrodes is covered with an electrolyte. The device is especially useful for detecting or monitoring sulfur dioxide in emission gases. A method of detecting or monitoring sulfur dioxide emissions using the electrochemical micro-sensor device includes contacting the emission gas with the sensor of the present invention, measuring the current output of the sensor, determining if the current output indicates the presence of sulfur dioxide, and generating a signal, that can be used to actuate a scrubber system when a pre-determined level of sulfur dioxide is detected.
An electrochemical micro-sensor device for detecting or monitoring sulfur dioxide comprising a substrate supporting an arrangement of a working electrode, a reference electrode, and a counter electrode, wherein a first portion of the electrodes is covered with an insulator, and a second portion of the electrodes is covered with an electrolyte, and wherein the electrodes and the insulator are applied to the substrate using a thick film technique.
