Dew Point Guard

Filter Elements/


Hygrometers/Dew Point Guard

Sensors that can meet the need for accelerated response and for measuring dewpoints in mildly corrosive gases. Ceramic sensors provide the fastest documented response to dewpoint changes.

Key Features
  • Digital Readout
  • Fastest Programmable Response Time
  • Integral Signal Conditioning
  • Dual Alarm Relays
  • Scalable 4 - 20 mA Output
  • NIST Traceability
  • Interchangeable Sensors
  • Optional Second Process Variable Input
  • NEMA 4 Front Panel Cover

EI offers a choice of user selectable dew point ranges:

  • -100 to +20°C
  • -148 to +68°F
  • 0-1,000 PPMV
  • 0-1,000#/MMSCF

EI also offers recalibration on sensors so that accurate dewpoint or humidity levels are controlled. Sensors that read incorrectly will result in high humidity downstream of the compressed air system.
