| SIGNET 2720 PRE-AMPLIFIER |
| |
| The Signet 2720
unity gain Pre-amplifier converts pH probe
signals to a level that can be wired over
a great distance on ordinary cable. The 2720
connects to the new line of Signet pH and
ORP sensors with a unique twist-lock connection
design. The 2720 was designed for use with
any device supplying a dual 5 VDC supply including
all current Signet models of pH and ORP controllers,
analyzers, and transmitters. The unit is fully
potted and features a 15 ft. shielded cable
and easy to connect 0.75” FNPT threads
for easy installation into submersible and
in-line (use threaded cap P31542) applications. |

The Signet 2714 and
2716 pH Electrodes feature a combination design
with measurement, reference, and temperature compensation
element in one package. The plastic body construction
and unique connection design makes removal and replacement
of the electrodes so simple it can be done in seconds.

electrode with unique integral ID resistor for automatic
sensor recognition by the Signet 8710 pH/ORP Transmitter.
The chemically resistant CPVC body, and twist-lock
connection make removal and replacement of electrodes
fast and simple.
