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

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 p lunger 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).
