PRODUCT DESCRIPTION

RAE Systems MultiRAE Pro Multi-Gas Monitor

The MultiRAE Pro is highly versatile, accepting up to 25 interchangeable sensors to monitor a wide range of hazards, including volatile organic compounds (VOCs), toxic gases, combustible gases and O2 levels, as well as gamma radiation. Its large, intuitive display and easily replaced sensors make it simple to use and calibrate, and 5 alarm types, including a low alarm, give you the flexibility to detect and respond to incidents quickly.

  • Intuitive display shows 1-3 hazardous gases at once
  • Flexible and customizable for different applications
