The ABB AX400 series delivers high-reliability process monitoring with advanced technology designed for diverse industrial applications. Supporting pH/Redox (ORP), conductivity, and dissolved oxygen measurements, the AX46x models offer continuous, dual-channel monitoring with exceptional accuracy.

Engineered for operational versatility, every AX400 analyzer includes two isolated current outputs and three programmable relays, assignable to key measurement parameters or calculated values.

With universal 85-265 V AC power support and optional 24 V AC/DC operation, the AX400 series minimizes service requirements and lowers compliance costs.

• Accessible Installation Terminals: Termination points are fully accessible, facilitating straightforward wiring and minimizing setup time.
• Dual-Input Measurement: Equipped with dual continuous measurement channels for real-time validation of process parameters.
• High-Speed Ammonia Breakthrough Detection: Enables precise evaluation of process changes before and after critical equipment.

In metal finishing facilities, precise control of pH and Redox (ORP) is critical for the safe and efficient removal of toxic chromium ions from wastewater streams. Implementing a dual-channel AX400 analyzer with integrated control allows operators to continuously monitor both pH and ORP simultaneously.
