Function of the cleaning device at the amperometric sensor
In the membrane-covered amperometric sensor, the working electrode is separated from the water and disinfectant by a most sensitive membrane. A cleaning device is not realizable. This membrane may be by substances, which are located in water, be contaminated. This contamination holds the molecules to be measured back and reduces the sensitivity of the measurement. Caused by the membrane, a membrane-covered amperometric sensor is sensitive to pressure. For some disinfectant there is the possibility, carry out the measurement without membrane. The missing membrane leads to a pressure stability of the sensor. At the same time this case, the working electrode is exposed, so that the surface can be cleaned mechanically.
