Honeywell QRAE II — multi-gas detector (O₂, combustible gases, H₂S, CO)
The Honeywell QRAE II is a compact, fully featured multi-gas detector supporting one to four sensors: oxygen, combustible gases, hydrogen sulfide and carbon monoxide. Available in a diffusion or pumped version, with a waterproof housing (IP-65), an easily replaceable battery and a modern SPE O₂ oxygen sensor (lead-free, RoHS-compliant). A large, rotatable graphic display makes it easy to read from the belt or in hand.

A large, rotating graphic display makes it easy to read from the belt or in the hand.
Note: The QRAE II is a previous-generation model; its successor in our offer is the QRAE 3 (incl. a wider selection of toxic gases and a pump with up to 30 m reach). The calibration station for the QRAE II is the AutoRAE Lite.
Key features
- From 1 to 4 sensors: O₂, combustible gases (LEL), H₂S, CO.
- Diffusion or pump version.
- Water- and dust-tight IP-65 housing; impact-resistant construction.
- SPE O₂ oxygen sensor — lead-free, RoHS-compliant, long life.
- Easy access to the pump, sensors, filter and battery.
- Li-Ion battery up to 14 h; cradle for PC and charging.

Frequently asked questions (FAQ)
Which gases does the QRAE II detect?
Oxygen (O2), combustible gases (LEL), hydrogen sulfide (H2S) and carbon monoxide (CO) — from one to four sensors.
How does the QRAE II differ from the QRAE 3?
The QRAE 3 is the newer generation: a wider selection of toxic gases (incl. NH3, HCN, SO2, PH3, Cl2, NO2) and a pump with up to 30 m sampling reach. The QRAE II covers O2, combustible gases, H2S and CO.
Which calibration station supports the QRAE II?
The AutoRAE Lite station performs automatic bump testing and calibration of QRAE II detectors (in the rechargeable-battery version).
