Sensors for oxidising substances (chlorine, chlorine dioxide, chlorites, ozone, peracetic acid, hydrogen peroxide, bromine, iodine, permanganate) in aqueous solutions including special electrodes and peculiar operating features; their selectivity, sensitivity, accuracy and reliability cannot be easily found in other analysers presently available in the market. The mechanical electrodes de-passivation system allows the use of these cells in all those applications where traditional cells could not work because of the presence of fouling substances that would deposit on the electrodes rapidly making the measure unreliable. Mod.606 cells have been designed for applications where selective and accurate oxidant analysis is a basic issue because the concentration to be detected is very low, or very high, or because high reliability for long operating periods with no maintenance needs is required. Another typical application of this cell is for oxidising substances measurements in sea water. These sensors are made of a polycarbonate through flow chamber that houses the measuring electrode, the counter electrode, the reference electrode, the optional temperature sensor for measurement thermo-compensation and the brush for mechanical electrodes depassivation. The electrodes are directly immersed into the sample that flows in the chamber with a constant flow rate, controlled by the cell itself; the electrodes are kept clean and active by the action of the brush.
