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 5700 or 8750 instrument. The 2721 should be used with special order sensors built with cables (Signet models 277X-HT or 277X-1-HT).

Fields of Application:

Design allows quick connect/disconnect of sensors
Pre-amplification for submersible and in-line installations
Unbreakable CPVC body
Designed for use with Signet pH & ORP Electrodes to assure signal integrity up to 120 m. (400 ft)
