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
