ABB launches ultra-accurate water quality analyzer and advanced multi-input transmitter

The AeroStar™ ULTRA and ULTRA TRACE sensors lower maintenance costs by up to 70 percent in applications where even trace levels of dissolved oxygen can compromise performance or cause corrosion.

ABB today announced the launch of two major innovations for continuous water analysis (CWA): the AeroStar™ family of dissolved oxygen sensors and the AWT424 transmitter. Together, these innovations set a new standard for precision, reliability, operational efficiency, and digital connectivity in water monitoring. The combined offering delivers a fully integrated, digital solution that helps customers operate more efficiently, sustainably, and safely.

Ultra-precise water quality measurement with AeroStar™

Compared to traditional electrochemical sensors that can require frequent sensor replacement, calibration and maintenance, AeroStar ensures stable, ultra-accurate water quality measurement with minimal maintenance in increasingly complex industrial environments, reducing unplanned downtime and cost.

Engineered for applications in the power, process steam, semiconductor, and food & beverage industries, where even trace levels of dissolved oxygen can compromise performance or cause corrosion, the new AeroStar ULTRA measures down to 4 parts per billion, while AeroStar ULTRA TRACE delivers measurement capability below one part per billion (ppb). The advanced luminescence quenching optical design offers stability and precision, with a fast response time and extended sensor cap life of up to two years – reducing maintenance by as much as 70 percent compared to traditional electrochemical devices.

“The new AeroStar sensors deliver ultra-low dissolved oxygen measurement with unmatched precision and reliability,” said David Martins, Technical Product Manager, Continuous Water Analysis with ABB’s Measurement & Analytics division. “Their robust design and digital connectivity make them the ideal solution for corrosion control in steam water systems and ultra-pure water applications, ensuring users can maintain process confidence while significantly reducing maintenance requirements.”
