Rosemount™ 398R Retractable pH/ORP Sensor

pH/ORP Sensor features a chemical-resistant design with Tefzel, titanium, and a robust reference junction.

The Rosemount 398RVP pH Sensor / ORP Sensor 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

Key Features

  • Superior chemical resistance allows pH sensor and 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 accurate pH/ORP measurement even in coating, fouling and poisoning processes
  • Helical reference pathway hinders reference poisoning and cracking resistant glass for a long pH/ORP sensor life
