Smart and Accurate Chlorine Control with ChloroStar™ Sensors and Accessories

ABB has unveiled the ChloroStar™ series, a cutting-edge line of sensors, transmitters, and accessories designed to deliver precise and reliable chlorine measurement. This innovation helps industries like water treatment and wastewater management achieve enhanced chlorine control, ensuring improved processing and reduced downtime.

Tackling Chlorination Challenges with Precision

Chlorination plays a critical role in eliminating harmful pathogens in water and wastewater. To meet stringent regulatory standards, industries require dependable measurement solutions. Traditional chlorine sensors often demand frequent maintenance due to issues like fouling and drift, which compromise performance. ChloroStar™ addresses these limitations with features that streamline operation and maintenance, ensuring consistent performance in challenging environments.

Key Benefits of ChloroStar™

The ChloroStar™ family offers:

• Self-cleaning sensors to minimize fouling.
• Modular design for flexible installation.
• Predictive maintenance tools to reduce downtime.
• Enhanced diagnostics for quick troubleshooting.

According to Nikodem Siwek, Global Product Manager for ABB Measurement & Analytics, “Accurate chlorination is vital for safe water treatment. ChloroStar™ ensures maximum availability and reliability of chlorine measurement devices while minimizing maintenance requirements.”
