The RAE Systems MultiRAE is the most advanced wireless portable chemical detector on the market. The MultiRAE's cutting-edge PID sensor detects volatile organic compounds (VOCs), and supports over 30 electrochemical, NDIR, and catalytic sensors to detect up to five additional threats. These include: toxic and combustible gases, oxygen deficiency/enrichment, and carbon dioxide. The MultiRAE's wireless capability elevates worker protection to the next level by providing safety officers real-time access to instrument readings and alarm status from any location for better visibility and faster incident response.

Industrial hygiene, personal protection, and multi-gas leak detection in industries such as:

  • Oil and gas
  • Chemical
  • Aviation (wing tank entry)
  • Shipping / Marine
  • Environmental
  • Pharmaceutical
  • HazMat response
  • Clandestine drug labs
More Features:
  • Easy maintenance with replaceable sensors, pump, and plug-and-play battery
  • Fully automated bump testing and calibration with AutoRAE 2
  • Wireless access to real-time instrument readings and alarm status from any location
  • Unmistakable five-way local and remote wireless notification of alarm conditions
  • Over 30 interchangeable sensor options, including 0.1 to 5,000 ppm PID
  • Intelligent sensors store calibration data, so they can be swapped in the field
  • Extensive on-board gas libraries (190 VOCs and 55 combustible gases)
  • Largest display in its class
  • Continuous datalogging (6 months for 5 sensors, 24x7)
