What do combustible gas meters detect?

• A. Flammable atmospheres
• B. Oxygen deficiency only
• C. Toxic gases
• D. Dust particles

Answer: (A)

Combustible gas meters are used to detect the presence of flammable gases and vapors in the air. They typically measure how concentrated those gases are and report it as a percent of the lower explosive limit (%LEL). This helps you know when an atmosphere is within the flammable range so you can take action—ventilate, stop ignition sources, or isolate the leak. They aren’t designed to measure oxygen levels, toxic gases, or dust particles. If you need to know about oxygen deficiency you’d use an oxygen meter; for toxic gases you’d use a toxic gas detector; and for dust you’d use a particulate detector. Some devices combine sensors, but a combustible gas meter’s primary role is identifying flammable atmospheres.
