is required to protect the relatively weak output
signal of pH & ORP electrodes from a wide variety
of electromagnetic interference common in industrial
environments. The +GF+ 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.). Our 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 +GF+ SIGNET 2721
