RAE Systems introduces the QRAE 3, one-to four-gas monitor in pumped or diffusion models. The QRAE 3 senors include Oxygen (O2), combustibles and toxic gases options of Hydrogen Sulfide (H2S), Carbon Monodixe (CO), Sulfur Dioxide (SO2), and Hydrogen Cyanide (HCN) for responders and workers subject to hazardous environments.

The QRAE 3 has wireless capability which enables access to instrument readings in real time. The QRAE 3 also includes Man Down alarm. Real time readings allow for faster response and better worker visibility. The ProRAE Guardian Safety System and the EchoView Host Mini-Controller Closed-Loop wireless systems can also communicate real time hazard readings for safety-enhancing wireless monitoring.
