Product Specs

The PHE-7451-15 is a combination pH sensor designed specifically for insertable use in process and waste water applications. The outer body material is PPS and has 3/4" MNPT(or optional 1" MNPT) front and rear facing threads. The double junction reference cell is highly resistant to electrode poisoning solutions, while the use of the non-fouling patented Porous PTFE liquid junction ensures a steady presence of reference electrolyte. The PHE-7451 assures a low maintenance service life in most applications. The concave sensor configuration (see drawing above protects the pH bulb from particulate matter and provides a cleansing flow without affecting critical line pressure characteristics. Use of the high temperature version is recommended where service temperatures continuously exceed 80°C.

What is the right PH electrode to be installed in a PVC, 4" pipe with Water at 500 GPM flow, and what the Conductivity sensor

Asked by: Jafam
Thank you for your inquiry about the pH probe. The PHE-7351-15 pH probe has threads at the tip to thread into a standard Tee fitting and is self cleaning. As for a conductivity probe, you can send an email to flow@omega.com and provide the conductivity range you wish to measure conductivity.
