AX411 Dual Channel Transmitter for 2-Electrode Conductivity Cell

Brand: ABB Group

The AX411 conductivity transmitter is designed for use with two ABB 2-electrode conductivity cells. The cost-saving transmitter measures conductivity or resistivity 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. Applications include demineralisation and reverse osmosis plants, semiconductor industry, power plants, biomedical and pharmaceutical industries and large steam-raising plants in the Pulp & Paper, Steel and Chemical inductries.
