Abstract
A simple potentiostat circuit for use in biasing a three-electrode electrochemical cell is described wherein a direct electrical connection is made between the sensing electrode and the reference electrode during normal operation of the cell. Preferably the electrical connection is a resistor. By selecting the resistive value properly, the zero gas current of the cell is eliminated without negatively affecting the response of the cell.
