Chlorine, Ozone, Chlorine dioxide

Two different technologies are available for monitoring free chlorine, ozone, chlorine dioxide or monochloramine. The choice of the technology depends on water treatment methods:

  • Amperometric three electrode system TRIDES: Treatment with free chlorine, chlorine dioxide or ozone. Dual channel system (chlorine and pH) will provide on-line conversion from hypochlorous acid to free chlorine without reagents.
  • Process photometers CODES: Work under the same conditions as the amperometric system. In addition they can be used for monochloramine. pH compensation is not necessary because the reagents contain a buffer solution.

Amperometric systems have lower cost of ownership (no reagents). Under unknown conditions (and at pH above 8.5) it is safer to use a photometer.

  • CHEMATEST portable photometer: A high precision portable photometer is needed for calibration in any case.
