Rosemount™ 398 pH/ORP Sensor

pH/ORP Sensor features a chemical-resistant Tefzel and titanium construction, ideal for harsh liquids.

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

Key Features

  • pH sensor / ORP sensor has superior chemical resistance and can withstand applications containing chlorine dioxide and a wide variety of organic solvents and oxidizing agents
  • Minimum maintenance due to reference junction technology ensures long pH/ORP sensor life in coating, fouling, and poisoning processes
  • Maximum pH/ORP sensor life due to helical reference pathway which hinders reference poisoning
