GF Signet’s 2721 pH/ORP Preamplifier is perfect for protecting the output signal of pH and ORP electrodes from a vast range of electromagnetic interferences typical in industrial environments. The 2721 is utilized if remote pre-amplification is needed (e.g. tank temperature >80oC) or when connecting a different manufacturer's electrode to the Signet 5700 or 8750 instrument. The Signet 2721 should be used with special order sensors built with cables (Signet models 277X-HT or 277X-1-HT).
