Which instrument is used to measure wind speed in duct systems?

• A. Thermometer
• B. Anemometer
• C. Barometer
• D. Hygrometer

Answer: (B)

Measuring airflow in duct systems relies on an instrument designed to quantify air velocity. An anemometer serves that purpose, detecting wind speed as air moves through the duct, which is essential for evaluating exhaust flow and ensuring proper operation of a dryer exhaust system. Different instruments measure related properties: a thermometer measures temperature, a barometer measures atmospheric pressure, and a hygrometer measures humidity. Anemometers come in forms such as vane-type handheld devices or hot-wire sensors, all aimed at capturing how fast the air is moving.
