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 employs 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 features a Porous PTFE liquid junction and a saturated
potassium chloride electrolyte. The porous PTFE 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. 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 PTFE liquid and a flat pH glass
membrane. It can be used to measure the pH of any moist surface, or can be inverted and used as
a “one-drop” electrode. Samples as small as 100 microliters can easily be measured using
this “inverted” technique.
The spear-point model PHE-1526 is a refillable combination pH
electrode with a 9.5 mm (0.37") glass body, porous PTFE 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.
