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.

Features and 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.

Field of application

The following list is a general representation of basically suitable applications for this product. Please contact your personal representative to discuss the use of the product in your individual application.

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

Waste Water Treatment

Very low-impact treatment for waste water

Our water treatment technology delivers thorough yet environmentally friendly waste water treatment. What's more, with precisely metered additives and optimised processes, you also save money.

Utility Water Treatment

It makes economic sense to reuse process water.

Why would you discharge water just because you've used it once? If this water is treated properly, it can be reused with ease, cutting costs in no time.

Cooling Water Treatment

Efficiency is everything in the cooling water circuit

Everything at ProMinent revolves around the perfect cooling water circuit, which needs to experience few losses over its long life. The precise metering of inhibitors and biocides and suitable filters make this possible.

Swimming Pool Water Treatment

Modern water treatment and disinfection processes enhance swimming enjoyment

The use of metering technology and water treatment solutions may vary considerably depending on the industry and application. Rely on our decades of experience and know-how to find the safest and most efficient solution for you.
