High performance pH/ORP measurements for your harsh applications
The Rosemount RBI pH/ORP Sensor features a multi-junction reference design, making it ideal for use in tough applications containing sulfides and other poisoning ions. The sensor is offered with various
configurations to meet a wide variety of installation requirements.
Ordering information
The Rosemount RBI pH/ORP sensor is built with a Kynar® body and is available with two configurations: a ¾-in. male national pipe thread (MNPT) in-line/submersion version allows the sensor to be used in pipe tees or to be submersed in a tank, and a retractable version allows variable installation through a ball valve.
High performance and robust design
. Superior chemical resistance provided by a rugged Kynar body and
selectable O-ring materials (EPDM, Viton®, or Kalrez™). . High pressure rating up to 150 psig (1,035 kPa).
. Maximize sensor life with multi-junction reference.
Ease of installation
. The in-line/submersion body features ¾-in. NPT front and rear facing process connections for direct installation into a process sample line or connection to a ¾-in. FNPT coupling extension pipe for
submersion.
