PH electrochemical electrode SB0A

electrolyteplasticprocess

Mod.Sb0A probes are designed for all those processes where glass pH electrodes would not be suitable, for example in fluids containing abrasive or fouling substances and in processes with high concentration of hydrofluoric or phosphoric acid. These probes are made of PP (PVDF on request) and have ½' F process connections; they are supplied c/w bracket and accessories for wall mounting and are extremely easy to install. An electrolyte reservoir housed in the upper cap assures long operating periods with no refilling requirements. This probe includes, besides the temperature sensor for measurement thermocompensation, separate electrodes: the antimony electrode is anular with flat surface and the reference is Ag/AgCl, with flat shaped diaphragm. A Viton brush with alternating movement keeps constantly clean the electrodes surfaces. The brush can be pneumatically or electrically actuated. The lower vessel, that is fixed to the probe through a threaded nut, can be used as calibration vessel. Measuring range: 1-13 pH Antimony (Sb) pH sensors are suitable for difficult applications such as: the measure and control of pH in sugar production (e.g. the pH control during carbonatation reaction); the measure and control of pH in the production of soap; control of pH in soap processing; pH measure and control in samples containing hydrofluoric acid; pH measure and control in samples containing phosphoric acid; pH analysis in fouling or abrasive samples; pH measure in presence of calcium hydroxide (limewater); measure of pH in sewage treatment plants; measure of pH in sludges and slurry; treatment of processing water in food industry; measure of lime in dairy industry.
