Confined Gas Monitor
VRAE by RAE Systems
VRAE is a hand held one-to-five gas monitor with built-in sampling pump and optional data log-
ging. Sensors include new RAE dual range 0-100% Volume and 0-100% LEL, oxygen, and three
or four smart, interchangeable toxic sensors may be added. The dual range combustible sensor
can monitor explosive gases in an oxygen-free environment at percent-by-volume levels. The
internal pump automatically shuts off and an alarm is activated if the remote probe tubing crimps
or liquid is sucked onto the field-replaceable filter.

QRAE by RAE Systems
The QRAE is a dedicated confined space entry monitor with an internal pump. Its durable,
rechargeable, standard Lithium-ion batteries provide a 12-hour day of detecting combustibles,
oxygen, hydrogen sulfide, and carbon monoxide. The extended duration Lithium-ion battery
option provides up to 18 hours of continuous operation.
Reliable plug-in “smart” sensors: Combustible, Oxygen, Hydrogen Sulfide, Carbon Monoxide »
Robust external casing for harsh environments, including a strong protective rubber boot, water and dust resis- »
tance, rugged ABS plastic/metal case, and protection from portable radio interference (RFI)
Ease of use with one-hand operation; one button calibration with auto zero capability »
Strong built-in sample draw pump, with a flow rate at 150cc/minoptional and collapsible remote sampling probe, »
prevents liquid flow into monitor and its patented security mechanism warns of sample tube crimping or blockage
