Insertion/Submersion Combination Electrodes
The PHE-7151 series combination electrodes are ruggedly constructed; the outer body is ABS with 3/4" MNPT threads at both ends. The maximum insertion length is 31.75 mm/1.25". Electrodes are annular PTFE liquid junction refillable and include 15 ft of cable with a BNC connector. For applications with temperatures up to 120°C (248°F), units are available in polyphenylene sulfide (PPS).***
These electrodes have a special plunger design allowing them to be mounted at any angle.
** Refill Solution: PHFS-7151-4, 4 oz bottle; PHFS-7151-16, 16 oz bottle
***For polyphenylene sulfide body, add suffix “-PPS” to part number and $50 to price
In-Line Disposable Electrodes
OMEGA™ in-line combination electrodes mount on standard pipe tees for continuous pH or ORP monitoring. The electrode is constructed in a PVDF housing with 1/2" MNPT threading. Probe insertion length is 25 mm (1") and is able to withstand pressure up to 150 psi. Three-meter (10-ft.) cable length and BNC connector are standard. Dimensions: 127 x 25 mm (5 x 10")
CPVC In-Line Disposable pH Electrodes
Also available, the CPVC In-Line Disposable Electrode is ruggedly constructed to withstand up to 100 psi. Probe insertion length is 51 mm (2") with 3/4" diameter. A 3/4" MNPT fitting is standard and is supplied with 3 m (10 ft.) of cable and a BNC connector. Dimensions: 168 x 25 mm (6.6 x 10")
Automatic Temperature Compensation is not required with ORP (Redox) electrodes.

What is the expected service life for a PHE-7351-15-HF? The probe is mounted in a half inch process cooling water line using a T union. There is approximately 2LPM of DI water flowing across the probe face.
Thank you for your question?
pH electrodes are fragile and have a limited life span. The general shelf life of a pH probe is 1 year however how long an electrode will last is determined by how well the probe is maintained and the pH application. The harsher the system, the shorter the lifespan.

Are these compatible with Rosemount 5081 & 3081 transmitters?
Thank you for your inquiry about the pH probes. Omega's pH probes have a standard BCN connector and if the transmitter in question have it as well, then, yes. If not, unfortuanately, they ar enot compatible.

Is this model able to a process with sulfuric acid and caustic soda? What are the connectors of ATC and PH in this model?
Thank you for your inquiry! This probe will be compatible with sulfuric acid and caustic soda. The probe has a BNC connector for the pH portion and lead wires for the ATC.
