Product Description

QRAE II Pump is a full-featured, rugged yet compact, one- to four-sensor gas detector with built-in powerful pump.

This gas detector has been made to provide continuous exposure monitoring of oxygen, hydrogen sulphide, carbon monoxide, and combustible gases for workers in hazardous environments.  

A range of accessories, including car-charger, is also available, at extra cost.  Watch the attached videos, for more detail, about what comes in the kit, how to change batteries and how to calibrate.

The accessory, AutoRAE Lite automatic calibration station for QRAE II enables fast and easy bump testing and calibration of the monitor. It streamlines the data download process, and saves calibration gas, so affording the lowest cost of ownership of any comparable product.


  • Plug-in sensors: oxygen, combustibles, hydrogen sulfide, carbon monoxide or sulfur dioxide
  • Intuitive simple-to-operate two-button user interface with built-in pump
  • Display can be flipped 180º with the push of a button for easy viewing from belt or hand
  • Multi-language support
  • One-button calibration with autozero capability
  • Loud 95dB audible alarm
  • Bright, red flashing visible alarm
  • Vibration alarm
  • Interchangeable drop-in Lithium-ion and alkaline battery packs


  • Patented SPE O2™ Oxygen sensor unique features:
    • Lead-free design that complies with RoHS directive
    • Extended life compared to lead-type electrochemical oxygen sensors, resulting in a low cost of ownership
    • Leak-free design, minimizing downtime
  • 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

Product Reviews

  1. Easy and accurate

    Posted by Michaelglync on 11th Jul 2017

    Excellent value, easy and accurate to use. Really pleased to have found one so economic

  2. Easy, accurate sampling for reagent tubes

    Posted by George on 14th May 2017

    Often, ensuring accurate volumes of sample air can be tricky..especially when using bellows type sampling pumps.
    This pump draws gas easily and accurately. It is compatible with many ranges of reagent tubes and its seals and valves will operate properly for many years, given careful use.
