Hollow cell for selective measurements of oxidising substances, compact and economic, Mod.608

Hollow cell for selective measurements of chlorine, chlorine dioxide, chlorite, ozone, peracetic acid, bromine, hydrogen peroxide, permanganate and other oxidising substances, compact and economic

Hollow cell for the measure of oxidising substances in aqueous solutions, having extremely simple and compact design and nevertheless excellent selectivity, sensitivity, accuracy, stability and reliability.
Typical applications of these cells are in drinking water plants, food and beverage industry, bottled waters industry, sea water swimming pools, thermal springs swimming pools; moreover, they can be succesfully used even for measurements in seawater.
The cell body, made of PVC include measuring electrode, counter electrode and reference electrode.
On request they are supplied c/w integral temperature sensor. The cell is available with or without integral electronic unit.
Meauring principle: 3 electrodes polarographic cell; electrodes are in direct contact with the liquid under measure and are kept active by the sample flow inside the cell.
Selectivity is obtained by imposing the correct polarization voltage across the electrodes.
The reference electrode is available in two versions, so that the cell is suitable to work even in harsh conditions.
Operating pH limits (only for measures of hypochlorites and chlorites): 6.0 to 7.7 pH
Thanks to the material chosen for the electrodes the cell is absolutely free of signal drift.
Remarkable small sample consumption (down to 15 l/h).
Measuring range: 0÷2000 ppb, 0÷10 ppm; the cells including integral electronic unit give a 0÷2 Vdc signal proportional to the concentration of the oxidizing substance under measure in the range 0÷10 ppm. High signal linearity is achieved in both versions.
