Honeywell QRAE 3 — portable multi-gas detector (up to 4 gases, with pump)
The Honeywell QRAE 3 is a portable multi-gas detector that measures oxygen, combustible gases and two selected toxic gases (incl. H₂S, CO, NH₃, HCN, SO₂). A configuration of 1 to 4 sensors and a built-in automatic pump (sampling up to 30 m) make it a universal tool for worker protection and confined-space monitoring. An optional wireless module enables remote, real-time monitoring of readings and alarms.
