DOSASens CL4.2

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

  • Measured variable(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 recorded with a factor of 9 of its reading; O₃ is measured; malfunctions may occur with membraneless chlorine electrolysis
  • pH range: 6-8
  • Pressure range: 0‒1 bar, no pressure surges and/or fluctuations permitted
  • Temperature range: 0‒45 °C (no ice crystals in the water)
  • Integrated automatic temperature compensation
  • Response time: T90 approx. 30 seconds
  • 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-U, semi-permeable membrane
