Disinfection solutions for all applications Disinfection solutions play a particularly important role in applications such as drinking water, industrial water treatment and swimming pools. In these applications, the focus is on safe and cost-effective water treatment and disinfection as a means of protecting people and systems. An appropriate disinfectant is added to the process in a waterworks, swimming pool, cooling tower or bottle cleaning facility. Due to their powerful disinfectant properties, chlorine and chlorine dioxide have established themselves as the state-of-the-art solution available worldwide. Ozone is often applied in the treatment process in waterworks and bromine is suitable for salt water applications such as ships' ballast water or fish farming. Complete measuring points The sensory mechanism uses the amperometric principle, i.e. the disinfectant concentrations are converted to electric currents in the sensor, which are then processed in the transmitter to obtain the required reading. To do this, the medium (mostly water) is supplied to the sensor via a flow assembly. The discharged medium is either returned under pressure or directed into the drain. This is referred to as a lost sample, a method commonly used in the field of drinking water for the prevention of all possible contamination.

Wide range of high-quality products Endress+Hauser offers a wide range of sensors. Besides the sensor for free available chlorine, sensors for chlorine dioxide, total chlorine, free bromine and ozone are available. The highly automated production process guarantees consistently high quality. Testing is also performed on a fully automated testbed, where the sensors are tested for zero point, slope and constancy and the results are documented.

Benefits • Wide range of sensors: free available chlorine, chlorine dioxide, total chlorine, free bromine and ozone • Easy installation thanks to complete measuring panels with flow assembly • Simultaneous measurement of pH and ORP values,

conductivity and oxygen possible • High-quality products guaranteed
