Abstract:
A method of adjusting the output of an electrochemical sensor including a working electrode and a counter electrode, includes: electronically causing a current flow between the working electrode and the counter electrode via an electrolyte without introducing a test analyte to the electrochemical sensor; measuring a response of the sensor to the current demand resulting from the electronically generated current flow; and using the measured response to adjust the sensor output during sampling of an analyte gas.
