Preamplifier
2721
Pre-amplification is required to protect the output signal of pH and ORP electrodes from a wide variety of electromagnetic interferences common in industrial environments. Signet 2721 is used if remote pre-amplification is required (e.g. tank temperature >80oC) or connecting another 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).
