Monitor Your Bromination Process Easily and Precisely with our Sensors

The membrane-covered, amperometric sensor works on the three-electrode principle; it is used for the online measurement of hypobromous acid (HOBr). The electronic components integrated in the sensors provide a temperature-compensated current signal (4 to 20 mA) or a Modbus RTU output signal.

The disinfectant bromine offers a greater disinfectant effect and higher pH value compared with chlorine compounds, while having a low 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 3-electrode principle; it is used for online measurement 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.

The sensor can be connected directly to indicating devices/transmitters/controllers. They supply the sensor with voltage and allow for easy calibration of the measuring system.

The sensor is not suitable for detecting the absence of bromine.
