The QRAE II is a full-featured, compact, one- to four-sensor gas detector for oxygen, combustibles, hydrogen sulfide, carbon monoxide or sulfur dioxide. Key features include easy-to-change battery pack, a water-resistant case and a new state-of-the-art O2 sensor.

Please note this instrument is coming to it's end of life.  AES will however, continue to support your QRAE II with service, repair, warranty replacement parts, or an equivalent product replacement until 30 June, 2019. 

  • Best EMI/RFI immunity technology for products in its class, eliminating radio interference
  • Easy access to pump, sensors, filter and battery compartment without exposing electronic components to potential damage
  • IP-65 water- and dust-resistant case
  • Strong, protective, concussion-proof design
