QRAE II Pump

The QRAE II is available as a diffusion or pumped one-to-four gas monitor for detection of combustibles, oxygen, hydrogen sulfide, carbon monoxide, or sulfur dioxide.

Key features include an easy-to-change battery pack, a water-resistant case and a new state-of-the-art O2 sensor.

Key Features

  • 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


Advantages

  • Plug-in sensors: oxygen, combustibles, hydrogen sulfide, carbon monoxide or sulfur dioxide
  • Intuitive simple-to-operate two-button user interface with built-in pump
  • Pump or diffusion models available
  • Cradle doubles as an external battery charger and data transfer connection
  • Rugged housing
  • Large graphic display for easy overview of gas type and concentration
  • Rechargeable Lithium-ion battery pack provides up to 14 hours of continuous operation
