Qrae 3 4 gas detector can optionally measure 4 of the following gases: LEL, OXYGEN, CO TOXIC GAS, H2S, NH3, CL2, NO2, SO2, HCN, NH3, PH3
QRAE 3 is a multifunctional, sturdy design, integrated 4 sensors in one machine and has 2 models: air pump type measurement and gas diffusion type measurement, the machine provides the ability to continuously monitor workers’ contact with O2, flammable gases, and toxic gases, including H2S, CO, SO2, HCN and response gases in toxic environments.
QRAE 3 has wireless connectivity that allows access to the machine to read data in real time and alert states (including low alert levels) from any location in the clearest and fastest way. Real readable hazards can also be transmitted to the ProRAE Guardian Safety System and the EchoView Host Mini-Controller Closed-Loop Wireless System which increases wireless monitoring.
