Abstract:
Apparatus (2) for sensing at least one parameter in water, which apparatus (2) comprises: (i) a dissolved oxygen sensor (4) for sensing dissolved oxygen in the water; and which apparatus (2) is such that: (ii) the dissolved oxygen sensor (4) has a working electrode and a reference electrode; and (iii) a voltage signal is applied between the working electrode and the reference electrode, and the voltage signal provides a conditioning waveform, then a wait time, and then a measurement function.
