Human: What are the differences between the various types of thermometers? Assistant: 
The most common type of thermometer is a glass thermometer, which typically has a bulb at one end and a stem that extends to the other. This type of thermometer can measure both temperature and humidity. Digital thermometers use electronic components to calculate temperature. These thermometers have more features than traditional glass thermometers, including an LCD display, memory, and alarms. Radiant thermometers measure air temperature by measuring the infrared energy emitted from the surface of an object. They are commonly used in industrial settings.
