Rosemount™ 396RVP pH/ORP Sensor
396R & 396RVP pH/ORP Sensor
The Rosemount 396RVP pH Sensor / ORP Sensor is specifically designed for improved life in harsh, dirty applications where a separate sample stream is difficult to provide and greater insertion depths are required.
This pH/ORP sensor is designed for use with a 1-1/4 in. or 1-1/2 in. ball valve for tap installation.

Features

  • Minimum maintenance due to robust reference technology helps ensure a steady signal when pH sensor / ORP sensor is coated
  • Retractable design for use with ball valve assemblies
  • Versatile mounting options feature either a 21" or 3" titanium tube sensor length
  • 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
  • Enhanced performance and increased pH/ORP sensor life with cracking resistant glass
