ORP Analyzer

The pH / redox (ORP) analyzer AX466 enables two continuous measurements of pH or redox (ORP) with simultaneous local display and retransmission. The AX466 is used with glass, enamel and antimony pH electrodes and metal redox sensors providing measurements with exceptional accuracy and performance. It incorporates the latest technology to provide a highly reliable, yet flexible, feature-packed device that satisfies a diverse range of process monitoring and control applications. Applications include water and waste-water treatment and process lines in Water, Power, Chemicals, Pharmaceuticals, Pulp & Paper and Food & Beverage industries.
