VRAE

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
