The PHE-7352-15 is a combination pH sensor designed for insertable use in process and waste water applications where greater pipeline penetration is required. The outer body material is PPS and has ¾ MNPT front and rear facing threads with 57.1 mm (2&frac14") insertion depth. The sensor features sealed double junction construction which is highly resistant to electrode poisoning solutions, (typically those with cyanide, ammonia, sulfide and heavy metals in appreciable concentrations). The use of the non-fouling patented Porous PTFE liquid junction ensures a steady presence of reference electrolyte. Coupled with the novel Plunger pH glass electrode design, this sensor assures a low long maintenance service life in most applications. Use of the high temperature version is recommended where service temperatures continuously exceed 80°C (176°F).

• Suitable for Severe Conditions
• Large Diameter Pipe Insertion
• Waste Water Pipeline Insertion

Rated 5 out of 5 by from Works well. Built in temperature sensor is nice. Much cleaner design than older model. Interested to see how long this sensor lasts in our steel pretreatment.

Rated 1 out of 5 by from Missing information The new Omega website sucks. It has less information than the old one did. For example, the data sheet for this pH sensor does not say that it needs a power supply and another component to make this sensor work. I know this because we had to buy all 3.

Item PHE-7352-15 pH probe; can I land cable to terminal strip and extend another 150 feet to controller PHCN-961 without amplifier? If so what cable do you recommend?

Asked by: johnM
Thank you for your inquiry. The maximum cable distance we recommend without an amplifier is 50ft.

I need to monitor the pH through the building automation system. Can this sensor produce a 4-20ma or 0-10vdc signal?

Asked by: John5646
No. This probe cannot produce a 4-20 mA or 0-10 VDC process signal. Review pH probe PHETX-600 instead.

How do the leads connect to a display/controller (BNC)?

Asked by: Tessa
Hello! Thanks for your question. This pH electrode has a female BNC connector that attaches to the male BCN connector on the controller. If the controller has a terminal connector instead of the BNC then you need an adapter part # ADAPTOR-BNCF-SL.

What material is the seal between the electrode and the sensor body made of?

Asked by: Anonymous
Thank you for your inquiry about the pH probe. The sensor body is made of PPS (or Ryton) and has a PTFE and FKM seal within the electrode tip.

Is this pH sensor a combination sensor (outputs pH and temperature)? Or does a temperature sensor need to be purchased in addition to this sensor?

Asked by: Vikram
Thank you for your inquiry. The pH probe when connected to a pH display or controller will display the pH and compensate for temperature, not display. Unless, your current display or controller has that option, then, it will display temperature as well.

I am going to use the PHE-7353-15 sensor in a pipeline with chlorinated brine at a temperature of approximately 80 and a pressure of 2 BAR. Do you recommend the use of this sensor under these conditions?

Asked by: Anonymous
Thank you for your inquiry on the pH probe. The flow conditions will be good for the pH probe, yet, the chlorinated brine, chemical compatibility is the responsibility of customers to checked against the wetted materials.

What display unit/trasnmitter would you recommend to go with this probe. I would prefer to power the unit with 110V AC and the unit need only be a simple display etc

Asked by: EJens
Thank you for your inquiry about the pH probe. You may look at the PHCN-37 pH controller that is powered by VAC voltage and can behave as a transmitter as well.
