RAE Systems QRAE Plus 4 Gas Meter
- One to four plug-in "smart" sensors.
- Oxygen, Combustibles, and 9 toxic sensor options.
- Integrated sampling pump.
- Rugged housing for harsh environments.
The QRAE Plus 4 gas meter is a one-to-four confined space gas detector/monitor with an intrinsically safe rating which is perfect for use in harsh environments due to its resistance to water, dust, and EMI.
It's tough, compact design has several user-friendly features such as simple button operation, a rechargeable/easily changeable battery pack (available in both alkaline and rechargeable versions) that provides up to 20 hours of continuous operation, and the option of substituting the H2S and CO sensors for SO2, NO, NO2, Cl2, HCN, NH3, or PH3 and a 16,000 point datalogging storage capacity for downloading to a PC.
One-to-four plug-in “smart” sensors:
Combustible, Oxygen, Hydrogen Sulfide, Carbon Monoxide
Optional substance-specific toxic sensors:
Sulfur Dioxide (SO2 ), Nitric Oxide (NO), Nitrogen Dioxide (NO2 ), Chlorine (Cl2 ), Hydrogen Cyanide (HCN), Ammonia (NH3 ), Phosphine (PH3 )
Rechargeable Lithium-ion battery pack
Provides up to 20 hours (more than 2 work shifts) of continuous operation
Rugged housing
Withstands use in harsh environments with a water and dust resistant case and strong protective rubber boot
Highly resistant to radio frequency and other electromagnetic interference
Strong, built-in sample draw pump with optional collapsible sample-probe
Also available in diffusion configuration
One-button calibration with auto-zero capability
Loud audible alarm
Bright visual alarm
Interchangeable Lithium-ion and alkaline battery packs
