Pre-amplification is required to protect the output signal
of pH & ORP electrodes from a wide variety of
electromagnetic interference common in industrial
environments. The Signet 2720 Pre-amplifier is installed
locally, at the sensing point, to maximize this protection
while allowing cable extensions up to 120 m (400 ft.).
Signet's unique twist-lock design simplifies installation and
maintenance by providing for the quick connection and
disconnection of electrodes. And the CPVC body is virtually
unbreakable for extended service-life in both submersible and
in-line applications. If remote pre-amplification is necessary
(e.g., tank temperature > 80° C), or if connecting to
another manufacturer's electrode, use the Signet 2721 Remote
Pre-amplifier.
