DULCOTEST® Chlorine Sensors

DULCOTEST® Chlorine Sensors

With the DULCOTEST® Chlorine Sensor Product Family, free Chlorine, organic compound Chlorine, Total Chlorine and Compound Chlorine can be measured. Herefore, there are three sensor-series each consisting of several sensor types for different measuring ranges.

Application areas

Selective or summary registration of Chlorine compounds

  • free Chlorine (Cl2, HOCl, OCl-)
  • organic compound Chlorine (e.g. Isocyanuric acid derivates)
  • Total Chlorine (Cl2, HOCl, OCl-, Chloramines, organic compound Chlorine)
  • Compound Chlorine (Chloramines, from the difference of total Chlorine and free Chlorine)


  • Use in most different water qualities (as to pH value, salt content, temperature, pollution charge)
  • Efficient process guidance through precise amperometric realtime measurement (short response times)
  • No disturbance through clouding or coloration thanks to amperometric measuring principle
  • Stable zero point
  • No disturbance through temperature influence due to integrated temperature compensation
  • Reduced dependence from flow and cross sensitivities thanks to diaphragm covered electrodes
  • Fast commissioning through short starting time
  • Long lifetime thanks to diaphragm-separated electrodes from the process surroundings as well as defined electrochemical conditions through electrolyte
  • Easy and cost-saving maintenance through diaphragm cap changing
  • Multiple connection possibilities to periphery: via double-conductor to 4-20 mA interface of DULCOMETER® D1C controller, to a measurement transducer type DULCOMETER® DMT for forwarding the signal to a programmable logic controller, or integration in Bus systems (PROFIBUS®, CANopen-Bus)

  • Short delivery times enable near-term replacement
  • Special adjustments and own label for OEM partners
