GF Signet 2720 pH Pre Amplifier

Pre-amplification 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 Twist-Lock 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 preamplification is necessary (e.g., tank temperature > 80

Deg C), or if connecting to another manufacturer’s electrode, use the +GF+ SIGNET 2721 Remote Preamplifier.
