Sensor for the measurement of dissolved ozone in water – with surfactant-resistant membrane.

• Measured variable(s): Ozone
• Calibration: at the controller, via analytical determination by DPD method
• Cl₂: OZ7H: increases the reading by 1.5%
• Cl₂: OZ7N: negligible
• ClO₂: with OZ7N 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
• Integrated automatic temperature compensation
• Response time: T90 approx. 50 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
