Type 2721 Remote pH/ORP Preamplifier
Pre-amplification is required to protect the output signal of pH & 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 > 80 deg C) or connecting another manufacturer’s electrode to the Signet 8750 instrument. The 2721 should be used with special order sensors built with cables (Signet models 277X-HT or 277X-1-HT).
