Signet 3-272X-XX-XX Preamplifier

Price: $367.20 - $492.70

2721 Preamplifier

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).

Fields of Application:
  • Water and Wastewater Treatment
  • Neutralization Systems
  • Scrubber Control
  • Effluent Monitoring
  • Surface Finishing
  • Flocculent Coagulation
  • Heavy Metal Removal and Recovery
  • Toxics Destruction
  • Sanitization Systems
Advantages:
  • Design allows quick connect/disconnect of sensors
  • Pre-amplification for submersible and in-line installations
  • Unbreakable CPVC body
  • Designed for use with Signet pH and ORP Electrodes to assure signal integrity up to 120 m. (400 ft)
