Abstract (en)
[origin: EP0281828A2] A greater operating convenience is achieved in the device by the fact that the device (1) is provided with an automatic apparatus (20) which determines the duration of treatment. The apparatus is controlled in dependence on the electrical conductivity, which no longer changes significantly, or the pH value of the treatment liquid (23). <IMAGE>
