The Honeywell RAEGuard 2 PID is a fixed photoionization detector (PID) that measures a broad range of volatile organic compounds (VOCs). The RAEGuard 2 PID operates on 10 to 28 VDC and provides an analog 4-20mA, three-wire signal output and RS-485 Modbus digital signal output.

The RAEGuard 2 PID uses an intelligent processing platform and digital sensor technology that supports multiple ranges and resolutions and is capable of environmental self-adaptation. Calibration and maintenance have been greatly simplified as the digital PID module can be easily removed in hazardous locations for calibration or maintenance.

The RAEGuard 2 PID has a graphic display and local sound alarm and LED light status indicator. In addition, Low, High, and Fault relays can be configured to trigger external alarms or process controls. A magnetic key interface enables the detector to be calibrated and operational parameters adjusted with the explosion-proof enclosure in place.

Some key applications for the RAEGuard 2 PID along with the PIDs involved include:

  • Benzene in refinery analyzer shelters
  • Ammonia in industry
  • Vinyl Chloride in chemical manufacturing
  • Toluene or Ammonia in semi-conductor plants
  • Chlorine Dioxide, Hydrogen Peroxide, Ozone in pulp and paper
  • Solvent and chemicals storage
  • Phenol and DME in pharmaceutical
  • Toluene in printing
  • Air quality
  • Methyl Ethyl Ketone in paint spray booths
  • Heat transfer fluids
  • Acetone, Xylene, Phenol in medical, pathology, histology lab
