Abstract
A method and apparatus for determining the operating condition of a gas sensor apparatus including an amperometric electrochemical sensor operating normally in a potentiostat mode. By coating the sensor with a conductive coating or by varying one or more operating conditions, a response of the sensor can be determined and compared with sensor response while operating normally. This testing enables abnormalities in sensor operation to be determined, and failure of the sensor to be predicted.
