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.

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.
