Self Cleaning Disinfectants Sensor

A newly developed automatic cleaning method for Potentiostatic sensors lowers the operational costs and improves the reliability of disinfectants measurement/dosage in safety critical applications. The newly developed Potentiostatic sensors for the most common disinfectants like Free Chlorine, Chlorine Dioxide, Ozone and Peroxide are least affected by coating in surface water and waste water applications, preventing safety critical incidents, such as over dosage of chemicals. In combination with the patented automatic cleaning system (ASR), maintenance and operational costs are kept to the minimum. The overall system has unrivalled high measuring availability, operates fully automatic and has long service intervals, which makes it ideal for installation in unmanned water works, cooling towers and safety critical applications, such as gate warning systems in industrial waste water treatment plants (figure 4) or desalination plants to protect sensitive instrumentation or processes against intolerable disinfectants concentrations.
