Checks for the absence of chlorine in drinking water in order to protect equipment; max. operating period in chlorine-free water: up to 4 weeks

• Measured variable(s): NaClO (sodium hypochlorite), Cl₂ (chlorine gas), electrolytically generated chlorine
• Examination: by means of analytic determination of chlorine by DPD 1 method. Calibrate the sensor with chlorinated water, establish a separate measurement circuit if required
• Interferences: Interferences: ClO₂, O₃, bound chlorine may increase the value measured, reducing agent may cause slope loss
• Resolution: 0.001 ppm
• pH range: 6.5‒9
• Pressure range: 0‒0.5 bar, no pressure surges and/or fluctuations
• Temperature range: 0–40 °C (no ice crystals in the water)
• Integrated automatic temperature compensation
• Response time: T90 approx. 2 min
• Flow rate: approx. 30 l/h, low flow dependence
• Shaft length: standard 195 mm, 205 mm (Modbus version)
• Connection: standard 4-pole plug, M12 female
• Material: PVC-U, PEEK, stainless steel 1.4571, microporous hydrophilic membrane
