Reduced Oxygen Breathing Device 3 (ROBD3)

The Environics® Series 6202 Reduced Oxygen Breathing Device 3 is the next generation system that simulates altitude exposure and can be utilized for both research and hypoxia training.  To be notified of the release of the ROBD2 retrofit package and the release of ROBD3, click here.

New Features of the ROBD3

  • 10.4" Color Touch Screen HMI (Human Machinne Interface)
  • Improved Pulse Oximeter Response Time
  • Ethernet Connectivity with Remote Operating Software
  • Remote communications are compatible between ROBD2 and ROBD3
  • Flows up to 90 L/min standard vs 50 L/min
  • Graph SpO2, Oxygen, Pulse and Altitude for up to 80 minutes
  • Review trend data with test subject after recovery
  • Easily create 16 programs with up to 12 steps each
  • Breathing bag housed within the system
  • ROBD2 may be upgraded to take advantage of these new features


As in the currently available ROBD2, the ROBD 3 uses Thermal Mass Flow Controllers (MFC) to mix breathing air and nitrogen to produce the sea level equivalent atmospheric oxygen contents for altitudes up to 34,000 feet. The MFC's are calibrated on a primary flow standard traceable to the National Institute of Standards and Technology (NIST). The system introduces pressure changes and gas expansion as a function of altitude. Several safety features are built into the device: prevention of over pressurization of the subject's mask, prevention of reduced oxygen contents below those being requested for a particular altitude and an emergency dump switch that will supply 100% O2 to subjects. The software is menu driven.  Built-in self-tests verify all system component functionality before the operation of the system can begin. If any self-test fails the system will not operate. The system is designed to work with both bottled gases and gases produced by a Nitrogen/Air Generator (available separately).
