Dial thermometers are devices used to measure temperature in a variety of applications. They consist of a metal stem or probe attached to a dial display that indicates the temperature in degrees Fahrenheit or Celsius. Dial thermometers come in a variety of types, including bi-metallic, gas-actuated, and liquid-filled.
Bi-metallic thermometers consist of two strips of metal with different coefficients of thermal expansion. As the temperature changes, the strips expand and contract, causing the dial to move.
Gas-actuated thermometers use a gas-filled bulb that expands and contracts as the temperature changes, causing the dial to move.
Liquid-filled thermometers use a liquid, typically mercury or alcohol, that expands and contracts as the temperature changes, causing the dial to move.
Dial thermometers are easy to use and require no complex calibration procedures. They are also rugged and durable (won't break when dropped or knocked) and can be used in harsh environments. To learn more, see our dial thermometers guide.
