Disinfectants are used in a variety of fields. Our online monitors with control functions are designed to meet specific demands, depending on the application.
Under unknown conditions (and at pH above 8.5) Swan recommends using a photometer.

Amperometric Disinfectant Monitoring

AMI Trides

Reagent-free monitoring for disinfectans such as hypochlorous acid, free chlorine, chlorine dioxide, ozone, bromine, iodine.

AMI Trides

Photometric Disinfectant Monitoring

The Codes-II Series for continuous online determination of disinfectants based on the DPD colorimetric method (EN ISO 7393-2; APHA 4500 Cl-G).

Free Chlorine, Hypochlorous Acid, Chlorine Dioxide, Ozone, Bromine, Iodine and Monochloramine

Applications: Potable Water, Swimming Pools, Cooling Water, Hot Water Loops and Effluent.

Free Chlorine, Monochloramine, Combined Chlorine and Total Chlorine

The solution for differentiated water chloramination monitoring.

Applications: Potable Water, Sanitary Water and Effluent.

Total Chlorine and Calculation of Dichloramine

Complete System for Concentrations up to 10 ppm.

Applications: Potable Water, Sanitary Water, Cooling Water and Effluent.

Ozone Monitoring

For pharmaceutical water storage and distribution systems. Ideal for proving the complete destruction of ozone before water use due to a low detection limit of 1 ppb and no sensitivity loss in absence of ozone.

Applications: Pharmaceutical Water
