AX416 Dual Channel Transmitter for 2-Electrode Conductivity & pH Sensor

Brand: ABB Group

The AX400 analyzers incorporate the latest technology to provide highly reliable, flexible, feature-packed devices that satisfy a diverse range of process monitoring and control applications. 

The complete range encompasses solutions for pH/Redox (ORP), conductivity and dissolved oxygen.

Models AX41x enable continuous measurements of one or two low-level conductivity points with simultaneous local display and retransmission. 

The analyzers are used with ABB 2-electrode conductivity cells providing measurements with exceptional accuracy and performance.
