THERMOMETERS
Thermometers are essential tools used to measure temperature accurately. There are various types of thermometers available, including
- mercury-based
- digital
- infrared thermometers.
Mercury-based thermometers, although less commonly used today due to safety concerns, consist of a glass tube filled with mercury that expands or contracts depending on the temperature.
Digital thermometers, on the other hand, provide quick and accurate temperature readings by using electronic sensors and displaying the results on a digital screen. These thermometers are widely used in households and medical settings due to their ease of use and reliability.
Infrared thermometers, also known as non-contact thermometers, measure temperature by detecting the thermal radiation emitted by an object. They are particularly useful in situations where contact with the object is not possible or safe, such as measuring the temperature of a person’s forehead.
Overall, these different types of thermometers cater to various needs and provide valuable temperature readings in different settings.
