Amperometric Chlorine Sensor MCL4.2 - Made in Germany

Product Detail Information

Chlorine Sensor CL4.2


Chlorine sensor with membrane-covered, amperometric 2-electrode system. For the measurement of free inorganic chlorine at constant pH.

Product description:
• Measurement: NaClO (sodium hypochlorite), Ca(OCl)2 (calcium hypochlorite), Cl2 (chlorine gas), chlorine generated by membrane-electrolysis,
• Calibration: at the controller, via analytical chlorine determination by DPD-1 method,
• Interferences: ClO2 is being registered with factor 9 of its measured value; O3 is registered; with membrane-less chlorine electrolysis interferences may occur,
• pH range: 6 ... 8,
• Pressure range: 0 ... 1 bar, no pressure surges or fluctuations,
• Temperature range: 5 ... 45 °C ,
• Integrated automatic temperature compensation
• Response time: T90 ca. 30 seconds,
• Flow rate: approx. 30 l/h, low flow-dependence,
• Shaft length: standard 175 mm, mA-Version 220 mm,
• Connection: standard 4-pole plug, for mA-version 2-pole terminal or M12 female,
• Material: PVC-U and semipermeable membrane

Areas of application:
• Fresh water free of surfactants and with constant pH

Scope of supply:
• CL4.2: sensor, membrane cap, electrolyte
