Product Description

The Rosemount 398R pH Sensor / ORP Sensor, with integral cable, features chemical-resistant construction of Tefzel™, titanium and a robust reference junction. This pH/ORP sensor is ideal for measuring pH in harsh process liquids like sour water strippers, pulp bleaching towers that use chlorine dioxide, and process streams containing a variety of organic solvents.

Features

  • 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 robust reference technology helps ensure pH/ORP sensor has a long life 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.
