Shown smaller than actual size.
MOST POPULAR MODEL HIGHLIGHTED!
⻬ Interfaces Directly with Most
Instrumentation that Accepts

⻬ Signal can be Run up to
305 m (1000')
⻬ Power Supply Available
in Three Styles
OMEGA Engineering offers pH
electrodes with integral preamplifiers
for laboratory or industrial
applications. These electrodes can
interface directly with equipment that
accepts a millivolt input signal with a
10 kΩ or greater input impedance,
PHE-1304, $33.
such as a data acquisition interface or
multimeter. The preamplifier converts the
high impedance millivolt signal of the
electrode into a low impedance signal,
enabling the signal to be run
up to 305 m (1000') without signal loss.
The electrode is supplied with
1 to 3 m (3 to 10') of coaxial cable,
depending on the model. If longer cable
lengths are required, simply splice on
extension cable. These preamplified
electrodes are available in a variety of
styles and can interface with any pH
meter, controller, transmitter, multimeter
or data acquisition system with a
one-to-one unity gain.
An accompanying power supply is available in
three styles: an encapsulated battery design, an
external battery style, and a style for use with an
external DC power source.
