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:

  • Greater disinfectant effect 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 BCR 1-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-calcium hypochlorite, or the use of BrCl.

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

Sensor type BRE3-CAN is available for the treatment of swimming pool water with BCDMH

Your benefits

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

Field of application

  • Water disinfection in cooling towers
  • Water disinfection in swimming pools and hot tubs
  • Disinfection of seawater
