Overview
Rosemount™ 398R Retractable pH/ORP Sensor
The Rosemount 398R pH Sensor / ORP Sensor, with integral cable, features chemical-resistant construction of Tefzel™, titanium, and a TUpH™ 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.
bleaching towers that use chlorine dioxide, and process streams containing a variety of organic solvents.
Benefits
* uperior 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 TUpH reference technology helps ensure pH/ORP sensor has a long life in coating, fouling and poisoning processes
* Helical reference pathway hinders reference poisoning and cracking resistant glass for a long pH/ORP sensor life
