RAE Systems QRAE 3 Water and wastewater pipe inspection system uses a single screw designQRAE 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), and carbon monoxide (CO) for workers and responders in hazardous environments. Optional sensors include sulfur dioxide (SO2) and hydrogen cyanide (HCN). The QRAE 3's wireless communications capability enables access to real time instrument
