Automated Process

The Virtual Operator walks the test subject through the complete process, from donning the mask to performing the fit test. It’s efficient, fast, and includes troubleshooting guidance for the user.

3 Testing Modes

  • Proctored Mode — A proctor oversees the testing process to ensure compliance with military protocols.
  • Fit Test Mask Mode — The system leads the test subject through every step, from putting on the mask to receiving real-time guidance during the test.
