Overview
The chemical-resistant construction of Tefzel™, titanium, and the patented TUpH™ reference junction make the Rosemount 398RVP the ideal sensor for measuring pH in harsh process liquids. This sensor is used to measure pH in sour water strippers, pulp bleaching towers that use chlorine dioxide, and process streams containing a variety of organic solvents.Benefits
* Superior chemical resistance allows pH sensor / ORP sensor to withstand applications containing chlorine dioxide and a wide variety of organic solvents and oxidizing agents
* Minimum maintenance due to TUpH reference technology helps ensure accurate pH/ORP measurement even in coating, fouling and poisoning processes
* Helical reference pathway hinders reference poisoning for a long pH/ORP sensor life
* Variopol (VP8) cable connection option, for quick cable-to-sensor release, eliminates cable twisting.
