Abstract
An electrochemical gas sensor testing device that includes a test signal generator that generates a multiplexed signal that includes a first test signal that includes alternating current (AC) and is free from a direct current (DC) component and a second signal that includes a DC bias voltage, an electrochemical cell that includes a counter electrode, a sensing electrode, and an electrolyte, the counter electrode and the sensing electrode being in electrical communication with the electrolyte and each other, the counter electrode being in electrical communication with the signal generator to receive the multiplexed signal generated by the signal generator, and a processor that receives an AC signal from the sensing electrode and that analyzes the AC signal.
