Bromine measurement with DULCOTEST sensors: Safe metering in disinfection processes with bromine. The robustness of the sensors makes them suitable for a very wide range of water qualities.

Product description

Reliable online measurement of bromine – with DULCOTEST sensors

Bromine compounds are an increasingly popular alternative to chlorine compounds in water disinfection in spite of the higher costs of the reagents.

Bromine has a number of advantages over chlorine compounds when it comes to disinfection:

  • More effective disinfection at higher pH values.
  • Lower volatility at higher temperatures.
  • Less tendency to corrosion.
  • Bromine compounds that have finished reacting (combined bromine) produce less odour and irritation of the mucous membranes.

Our product line of DULCOTEST bromine sensors provides three types of sensor for your measurement tasks.

Sensor types CBR1-mA and BCR1-mA are resistant to contaminated water and are designed for the treatment of cooling water. Type CBR1 is specifically designed for free bromine from inorganic bromination processes, e.g. sodium bromide + sodium hypochlorite, or the use of BrCl.

Sensor type BCR1-mA is optimised for the measurement of organic bromination agents (e.g. BCDMH).

Sensor type BRE3-CAN is available for the measuring and control system DULCOMARIN for treating swimming pool water with BCDMH.

Your benefits

  • Precise, real-time amperometric measurement for efficient process control (short response time).
  • Suitable for a very wide range of water qualities (contamination, pH, salinity, temperature).
  • Amperometric measuring eliminates interference caused by turbidity or colouration.
  • Stable zero point means no drift.
  • Integrated temperature compensation eliminates interference caused by influence of temperature.
  • Diaphragm-covered electrodes for reduced dependence on flow, substances in water and film-forming media.
