The disinfectant bromine offers a greater disinfectant effect at higher pH values compared to chlorine compounds while at the same time having a lower corrosive effect.
Abreacted bromine solutions irritate the mucous membranes to a lesser extent and have a neutral odor.  

The membrane-covered, amperometric sensor works on the three-electrode principle. The device is used for the online measurement of hypobromous acid (HOBr).
Suitable bromination methods include free bromine (HOBr) as well as 1-bromine-3-chlorine-5.5-dimethyl-hydantoin (BCDMH).

Depending on the type, the electronics integrated in the sensors provide a temperature-compensated current signal (4 to 20 mA) or a Modbus RTU output signal.
A downstream device (indicator, controller, recorder, PLC, etc.) is used for calibration.
