RAEGuard 2 PID is a fixed photoionisation 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. 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.
