Colorimetric process analyzer (DPD-method) for measurement and dosing control of disinfectants such as free chlorine, monochloramine, total residual chlorine and combined chlorine.

  • For the continuous online determination of disinfectants based on the DPD colorimetric method (EN ISO 7393-2; APHA 4500-Cl G).
  • Measurement values : free chlorine, monochloramine, total residual chlorine, combined chlorine, flow and if installed pH and temperature.
  • Complete system including measurement and control electronics, photometer, flow indicator, reaction chamber, reagent dosing system and reagent containers.
  • Integrated pH measurement with temperature compensation (available as option).
  • All usual dosing devices for disinfectants and pH control can be connected either through relays or analog output signals. Two independent controllers can operate simultaneously.
