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 non­fouling 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 on
the right) 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 (176°F).
