AX433 Dual Channel Transmitter for 4-Electrode Conductivity Cell

Brand: ABB Group
Request Information
Favorite

The AX433 conductivity transmitter enables two continuous measurements of mS/cm conductivity with simultaneous local display and transmission via analog outputs. 

The transmitter is designed for use with ABB’s 4-electrode conductivity cells to measure with exceptional accuracy and performance. 

It incorporates the latest technology to provide a highly reliable, flexible, feature-packed device that satisfies a diverse range of process monitoring and control applications.
