What instrument is used to measure temperature?

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

Answer: (B)

Measuring temperature requires an instrument that responds to thermal energy and gives a reading of hot or cold. A thermometer is designed for this purpose, using a liquid expansion, a bimetallic mechanism, or a digital sensor to translate temperature into a readable value. In HVAC work, you’ll use thermometers to check supply and return air temperatures, as well as indoor air temperature. Barometers measure atmospheric pressure, hygrometers measure humidity, and anemometers measure air velocity. Because each of these instruments gauges a different property, they don’t provide a temperature reading.
