Abstract
The present disclosure relates to an amperometric sensor for determining measurement values of a measurand representing a chlorine dioxide content of a measuring fluid, the sensor including a sensor housing in which a housing chamber is formed, a membrane sealing the housing chamber, a working electrode arranged within the housing chamber, a counter electrode arranged within the housing chamber, an inner electrolyte contained in the housing chamber and in contact with the membrane, the working electrode and the counter electrode, the inner electrolyte having a pH value between 3.5 and 9, inclusive, and a pH buffer stabilizing the inner electrolyte. The sensor further includes a measurement circuit electrically connected with the working electrode and the counter electrode and configured to apply a predetermined, constant voltage between the working electrode and the counter electrode and to generate at least one measurement signal representing a measurement value of the measurand.
