Water Disinfection Measuring System

The measuring system includes everything needed for disinfectant measurement: instrument, sensor, assembly and wiring – pre-mounted on a measuring panel. The system is used for measuring free Chlorine, Chlorine dioxide, Ozone or Hydrogen Peroxide. Measuring parameter and measuring range can be chosen in the menu. The integrated armature ensures a constant flow of approx. 30 l/h. As a consequence the system provides stable, precise and reliable measuring values. Flow fluctuations are not any longer shown up in the measuring curves as long as a water inlet flow of above 35l/h is guaranteed. For measuring free Chlorine, Chlorine Dioxide or Ozone a double gold sensor is used, for measuring in brine a special graphite-platinum sensor is available. For the measurement of Hydrogen Peroxide, a double platinum sensor is used. Temperature and flow is guarded by a further sensor, which additionally can be used for grounding. The control unit with touch screen operation includes an input for the measurement and temperature, one digital input, one analogue output and alarm relay, as well as an automatic sensor cleaning. Optionally, a system with integrated pH-measuring electrode is available which compensates pH fluctuations. The complete system is pressure resistant up to 6 bars at 20°C.
