摘要
An amperometric sensor circuit for measuring chlorine concentration in water. The circuit includes first and second working electrodes coated with a hydrophilic membrane. A power supply and biasing circuit is configured to deliver a generally constant voltage between the first working electrode and a reference electrode and to generally deliver a constant current between the second working electrode and a counter electrode. A measurement circuit measures the current between the counter electrode and the first working electrode. A processing circuit is provided for determining the chlorine concentration based on the current measured by the measurement circuit.
