The colorimetric process analyzer uses the DPD method for the continuous, online measurement and dosing control of various disinfectants, including free chlorine, hypochlorous acid, chlorine dioxide, ozone, bromine, iodine, and monochloramine. This method complies with EN ISO 7393-2 and APHA 4500 Cl-G standards, ensuring reliable and accurate results.

Designed for use in treated water, the analyzer is suitable even when additives like corrosion inhibitors, cyanuric acid, or antiscalants are present. It measures key disinfectants such as free chlorine, chlorine dioxide, bromine, iodine, ozone, and monochloramine.

The complete system includes measurement and control electronics, a photometer, flow indicator, reaction chamber, reagent dosing system, and reagent containers. An optional integrated pH measurement with temperature compensation is also available. The analyzer supports connection to common disinfectant and pH dosing devices via relays or analog signals, with two independent controllers that can run simultaneously for flexible operation.

Options:

• pH option containing pH sensor, temperature sensor, cables and electronics board
• Third signal output selectable as:
  • Current signal output
  • Interface RS485 (Profibus DP or Modbus)
  • Logger download kit (with HyperTerminal)
• Chemical cleaning module
