An amperometric sensor includes a first electrode, a second electrode and a reference electrode. The sensor further includes a switch to selectably electrically connect the first electrode as a working electrode and to electrically connecting the second electrode as an auxiliary electrode during a first time interval. During a second time interval, the switch electrically connects the first electrode as the auxiliary electrode and electrically connects the second electrode as the working electrode. The switching of the two electrodes is repeated continuously as amperometric measurements are performed. Preferably, the sensor includes an ultrasonic transducer proximate the working electrode and the auxiliary electrode to clean the electrodes.
An amperometric sensor comprising:
An amperometric sensor comprising:
An amperometric sensor that includes an ultrasonic transducer proximate to a working electrode and an auxiliary electrode to apply ultrasonic energy to the working electrode and the auxiliary electrode continuously or intermittently to remove the buildup of salts or organics on the surfaces of the working electrode and the auxiliary electrode.
An oxidation reduction potential sensor that includes an ultrasonic transducer proximate to a sensing electrode and a reference electrode to clean the sensing electrode and the reference electrode by applying ultrasonic energy to the sensing electrode and the reference electrode.
A sensor comprising no more than three electrodes that performs conductivity measurement, amperometric chlorine or bromine measurement and measurement of oxidation reduction potential.
A sensor comprising only two electrodes and a pH sensor having a reference electrode that performs conductivity measurement, amperometric chlorine or bromine measurement, pH measurement and oxidation reduction potential measurement.
