HONEYWELL RAE SYSTEMS QRAE 3
Versatile Compact wireless monitor for up to four gases
Model: QRAE3
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.
Features and Benefits:
- Real-time gas detector readings and alarm status enabled by state of the art wireless technology
- Unmistakable five-way local and remote wireless notification of alarm conditions
- Intuitive simple-to-operate two-button user interface
- Strong, protective, concussion-proof design
- IP-65/67 water- and dust-resistant case
Gases Detected and Sensor Range:
- CO – 0 to 500 ppm
- H2S – 0 to 100 ppm
- O2 – 0 to 30.0% VOL
