    摘要: Apparatus (2) for sensing at least one parameter in water, which apparatus (2) comprises: (i) at least one electrode based sensor (4, 6) for sensing at least one parameter in water; and which apparatus (2) is such that: (ii) the electrode based sensor (4, 6) has a self-cleaning electrode; (iii) the electrode based sensor (4, 6) has a reference electrode; (iv) the self-cleaning electrode is stable in water; (v) the apparatus (2) is configured to operate by liberating chlorine from the water using a first waveform applied to the self-cleaning electrode; (VI) the apparatus (2) is configured to operate by liberating chlorine and oxygen from the water using a second waveform applied to the self-cleaning electrode; and (VII) the apparatus (2) is configured to preserve the condition of the reference electrode by periodically regenerating the reference electrode.
