Which statement is true about all MultiRae Pro models?

• A. They detect Chlorine Gas and Sulfur Dioxide
• B. They detect Oxygen and LEL
• C. They detect Hydrogen Cyanide and Ammonia
• D. They detect Ozone and Nitrogen Dioxide

Answer: (B)

Baseline sensors on the MultiRAE Pro are oxygen and a combustible-gas (LEL) sensor, and these two are included on every model. Oxygen sensing is essential for safety in confined spaces, helping you detect hypoxia or oxygen enrichment. The LEL sensor tracks combustible gases as a percentage of their lower explosive limit, which is crucial for identifying flammable gas hazards before they reach dangerous levels. The other gas options listed—such as chlorine and sulfur dioxide, hydrogen cyanide and ammonia, or ozone and nitrogen dioxide—can be added as optional sensors, but they are not guaranteed on every unit. So, the statement that holds true for all models is that they detect Oxygen and LEL.
