Model PR20 Retractable Fitting

With pH measurements in chemical processes, a combined pH/Reference electrode is usually mounted in a by-pass flow fit-ting, a flanged immersion fitting or an on-line retractable fitting.

Applications for the PR20 retractable fitting can be found in all processes where the pH sensor should be removed without interrupting its continuity (e.g. pulp slurries, pressurized systems). The Yokogawa design ensures the safe retraction of the electrode from the process without shutting it down.

 Designed to make safe retraction under process pressure possible by blocking the ball-valve handle.

 Adjustable insertion depth for optimal positioning in the process.

 Integrated Pt1000 temperature sensor and liquid earthing.

 Easy replacement of the combined pH electrode.

 Damped probe retraction by o-ring friction with pressurized systems.

 Adaptable to most installations by a range of options.

 Optional flush ports for cleaning or calibration purposes.

 Compatible with Yokogawa sensor diagnostics.
