pH ELECTRODES
pH Electrodes
OMEGA’s glass-bodied, refillable
(RF), combination pH electrodes are
for general purpose laboratory
measurements. The inert nature of the
glass body allows these electrodes to
be used in aqueous and non-aqueous
solutions at temperatures up to 110°C (230°F).
The PHE-1479 has a ceramic liquid junction and a saturated potassium chloride electrolyte. This electrolyte is a laboratory standard
and is suitable for most measurements.The ceramic junction has a low flat rate which minimizes sample contamination from the
potassium chloride solution.
The PHE-1478 has a Porous Teflon®liquid junction and a saturated potassium chloride electrolyte. The Porous Teflon®liquid junction
provides a stable, non-fouling reference contact ideal for the most demanding applications.This research grade electrode should be
used when the sample has a very low or very high ionic strength, where greases or oils are present, or in biological solutions containing
TRIS or large amounts of protein.

Specialty pH Electrodes
These specialty electrodes are designed
for surface and subsurface measurements
of semi-soft materials. The typical
applications include meats, cheese, dairy
products, photographic emulsions and
electrophoresis gels.
The PHE-1525 Flat style is a refillable
combination pH electrode with a polymer
body, Porous Teflon
®
liquid and a flat pH
glass membrane. It can be used to
measure the pH of any moist surface
or inverted and used as a “one-drop”
electrode. Samples as small as 100
microliters are easily measured with
this inverted technique.
The PHE-1526 Spear-Point is a
refillable combination pH electrode
with a 9.5 mm (0.37") glass body,
Porous Teflon
®
liquid junction and
pointed pH glass bulb. It is designed
for sub-surface measurements
of cheese, processed meats and
other soft materials. These
electrodes respond quickly
and are easily cleaned.
