Sensor type BCR for bromine - dirt-insensitive DULCOTEST®
The new amperometric sensor BCR1, available from July 2012, has been specifically developed for the online measurement of the bromine concentration of organic disinfectants, like BCDMH (1-bromo-3-chloro-5.5-dimethylhydantoin), in polluted water.
BCR1 has greater tolerance to biofilms and other deposits. The membrane-covered sensor guarantees reliable measurements in cooling water circuits, in conjunction with special cooling water controllers and is being showcased for the first time on Stand J94 in Hall 8 at ACHEMA 2012.
Reliable measurement of organic bromination agents
The BCR1 type of sensor has been specifically designed for the "treatment of cooling water and waste water" and is not affected by common cooling water treatment chemicals, not even by the more usual higher pH values of up to 9.5. The sensor is used to measure free and bound bromine (in the form of bromamines) and organic bromination agents, like BCDMH and its by-products containing chlorine and bromine.
An innovative membrane electrolyte system prevents the premature blocking of the sensor membrane and also guarantees a satisfactory sensor service life even when used with media with biological activity.
The sensors are operated in a bypass to the main line up to a maximum back pressure of 1 bar and are compatible with ProMinent bypass valves. The sensors can also be operated with the majority of ProMinent controllers.
