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.
