Which statement about the MultiRAE Pro is true?

Which statement about the MultiRAE Pro is true?

• A. It is intended for oxygen-deficient environments only
• B. It is intended for normal atmosphere and readings will be affected if oxygen is deficient
• C. It does not monitor VOCs
• D. It can only monitor two threats at a time

Answer: (B)

The device is designed to operate best in normal atmospheric conditions, with sensors that expect typical oxygen levels. When the environment becomes oxygen-deficient, readings from several sensors—especially electrochemical ones—can become unreliable or less accurate. That’s why the true statement notes that readings will be affected if oxygen is deficient. The MultiRAE Pro actually monitors multiple threats at once, including VOCs, and is not limited to oxygen-deficient environments. The other options are inaccurate because the instrument does monitor VOCs, is not restricted to two threats, and is not intended only for oxygen-poor environments.
