The RAE Systems 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 includes a large graphical display with an icon-driven menu and intuitive, simple-to-operate, two-button user interface. The display can be flipped 180˚ to improve visibility whether clipped to the belt or held in the hand. A powerful 5-way alarm ensures dangerous conditions are known. The QRAE 3 has a strong, protective, concussion-proof design with an IP65/67 water- and dust-resistant case for use in difficult environments.

The QRAE 3 can deliver wireless real-time instrument readings and alarm status 24/7. This provides better incident visibility and can improve response time. The integrated wireless option allows the device to be used either in a closed loop system (compatible with EchoView host) or with ProRAE Guardian, Real-Time Wireless Safety System.
