Rosemount™ 397 pH/ORP Sensor & Quik-Loc Kit

pH/ORP Sensor provides high-performance in solutions with suspended solids.

The Rosemount 397 pH Sensor / ORP Sensor offers high performance pH and ORP measurements in aqueous solutions with high suspended solids. The pH/ORP sensor features a large area, polypropylene reference junction for maximum resistance to process coatings generally found in harsh, dirty and high solid applications. In addition, the secondary helical reference pathway serves as added protection from poisoning ions. The Rosemount 397 pH/ORP Sensor is specifically designed for use with the Quik-Loc Kit and is only available without an integral preamplifier.

Key Features

  • High performance in process solutions with high solids content
  • Improved pH/ORP sensor life and reduced maintenance due to the polypropylene reference junction and helical reference pathway
  • Crack resistant glass
  • Quik-Loc Kit consists of an adapter and a coupler - enabling the Rosemount 397 pH/ORP sensor to fit into the 1 in. MNPT coupler for quick disconnection without sensor cable twisting
  • pH sensor / ORP sensor is housed in a highly chemical resistant polypropylene body and completely sealed with EP (ethylene propylene) to eliminate process intrusion
