VRAE
Overview

The VRAE is a powerful hand held one-to-five combustible gas monitor with built-in sampling pump and optional data logging.
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 – regardless of oxygen levels.
The VRAE is capable of monitoring either combustibles, oxygen and three toxic gases or combustibles and four toxic gases. Its durable Nickel-Metal-Hydride batteries, powerful internal pump and rugged frame make it ideal for leak detection and site surveys.
Available Toxic Sensors include:
- Carbon monoxide (CO)
- Hydrogen sulfide (H2S)
- Sulfur dioxide (SO2)
- Nitric oxide (NO)
- Nitrogen dioxide (NO2)
- Chlorine (Cl2)
- Ammonia (NH3)
- Hydrogen cyanide (HCN)
- Phosphine (PH3)
- LEL
- Oxygen
- Ethylene Oxide
