Rae Systems QRAE 3 Diffusion (Non-Wireless)

Rae Systems QRAE 3 Diffusion Gas Detector (868MHz)

From: £592.99

QRAE 3 Diffusion Gas Detector Series (868MHz)

This QRAE 3 Diffusion gas detector offers a versatile, rugged, one to four sensor solution 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); ideal 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.

The wireless QRAE 3 monitor provides safety officers and commanders real-time remote access to the readings and alarm status of workers and responders. Safety officers who are outside the immediate incident area can have the same real-time situational awareness as those in the “hot zone.” This can help facilitate faster, data-driven decision making to alert responders, save lives and protect assets.

Applications include: industrial safety, confined space entry, multi-gas leak detection, environmental remediation, refinery turnarounds, fireground and HazMat response.
