The QRAE 3 provides detection and monitoring of Oxygen (O2), Combustibles, and toxic gases that include Hydrogen Sulfide (H2S), Carbon Monoxide (CO), Sulfur Dioxide (SO2) and Hydrogen Cyanide (HCN). QRAE 3 can deliver wireless real-time instrument readings and alarm status 24/7. This provides better incident visibility and can improve response time.
