General Purpose 1⁄2 MNPT pH Sensor

Dimensions: mm (inch)

PHE-7357-10

Applications

U Potable Water Supplies
U Cooling Towers
U Fresh and Salt Water Aquariums
U Secondary Treated Waste Water

The PHE-7357 sensor is designed for use in
most water and waste water applications.
The large reservoir of reference electrolyte,
coupled with the non-fouling nature of the
Porous PTFE liquid junction, assures a long
life in general service.

The sensor body reduces the risk of accidental
breakage during installation and maintenance
by the inclusion of protective lobes around
the sensing element. Also available for ORP
measurement.

Use of the high temperature version is
recommended where service temperatures
exceed 80°C (176°F).

PHE-5551 is a double-junction construction
with solution ground in a robust PPS housing,
being highly resistant to electrode poisoning
solutions. Standard on these elctrodes is a
110°C (230°F) rating.
