RAE Systems QRAE 3 Four Gas Monitor

MODEL# PGM-2500, PGM-2560

  • Provides monitoring of Oxygen (O2), Combustibles (LEL), and toxic gases.
  • Toxic gas options include Hydrogen Sulfide (H2S), Carbon Monoxide (CO), Sulfur Dioxide (SO2) and Hydrogen Cyanide (HCN).
  • Available in Diffusion or Pumped version.
  • Continuous datalogging (3 months for 4 sensors at 1-minute intervals, 24/7)
  • Easy access to pump, sensors, filter and battery compartment.

QRAE 3 is a versatile, rugged, one- to four-sensor pumped or diffusion gas monitor that provides continuous exposure monitoring of oxygen (O2), combustibles, and toxic gases, including hydrogen sulfide (H2S), carbon monoxide (CO), sulfur dioxide (SO2) and hydrogen cyanide (HCN) for workers and responders in hazardous environments.

The QRAE 3’s wireless communications capability enables access to real-time instrument readings and alarm status (including man-down alarm) from any location for better visibility and faster response. Real-time hazard readings can also be communicated to the ProRAE Guardian Safety System and the EchoView Host Mini-Controller Closed-Loop Wireless System for safety-enhancing wireless monitoring.
