DOSASens CL4.2

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

  • Measurand(s): NaClO (sodium hypochlorite), Ca(ClO)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,
