ABB has launched ChloroStar, a family of sensors, transmitters, and accessories for accurate and reliable chlorine measurement and analysis that enable users in the water, wastewater and other industries to control chlorine more efficiently, enhancing treatment and increasing process uptime.

With the removal of potentially harmful pathogens being critical for both potable and wastewater quality, strict regulations govern chlorination treatment in utility and industrial applications. To date, chlorine measurement and analysis has been challenging, with many sensor technologies requiring time-consuming maintenance to resolve issues such as fouling and drift that have affected sensor performance.Source: ABB

The ChloroStar family of chlorine analyzers addresses this challenge. With self-cleaning and resilient sensors, modular installation, predictive maintenance, and diagnostics, these devices make it quicker and easier than ever to achieve accurate measurements and maximum uptime of the chlorine dosing process, while ensuring that sensor maintenance costs are kept to a minimum.

The ChloroStar comprises two components – the ChloroStar Digital Sensor and the ChloroStar Cell.

The ChloroStar Digital Sensor is an intelligent tri-electrode sensor for the measurement of free or total chlorine. Featuring in-built diagnostics, pH compensation and EZLink connection technology, the unit provides reduced drift and increased accuracy, while the membrane-covered design minimizes cleaning and removes the need for additional sample buffering. The sensor is designed for use with ABB’s innovative InFlow Multi-Cell, a modular flow-cell system which delivers stable chlorine measurement independent of variations in sample flow. An industry-leading measurement of 1 l/hr (0.26 gal/hr) makes it ideal for applications in drinking water treatment, distribution, or closed loop systems.

The ChloroStar Cell is a fast reacting direct-contact electrode sensor with self-cleaning technology for the measurement of disinfectants such as chlorine and chlorine dioxide. Its innovative open-cell flow-through design uses the sample flow to continuously clean the electrodes, preventing blocking and clogging that affect other sensor types. The cell also reduces operational expenditure through 20% lower consumables cost compared to conventional solutions.
