Sensor for the measurement of dissolved ozone in water.

• Measured variable(s): Ozone
• Calibration: at the controller, via analytical determination by DPD method
• Interferences:
  • Cl₂ with OZ10H this results in a 1.5% increase in the reading
  • Cl₂ with OZ10N is negligible
  • ClO₂ with OZ10N this results in a 6% increase in the reading
• pH range: 2-11
• Pressure range: 0‒1 bar, no pressure surges and/or fluctuations
• Temperature range: 0‒45 °C, autom. temperature compensation integrated
• Response time: T90 approx. 15 s
• Flow rate: approx. 30 l/h (low flow dependence)
• Shaft length: standard 175 mm (mA version up to 220 mm)
• Connection: standard 4-pin plug; mA version 2-pole terminal, M12 socket or modbus RTU with M12 socket
• Material: PVC, semi-permeable membrane
