Lesson Content
Types Of Thermometer
A thermometer is an instrument used to measure temperature. There are different types of thermometers based on their use and design:
The following are examples of thermometers:
- Clinical Thermometer: Used to measure body temperature.
- Digital Thermometer: Provides a digital reading of temperature.
- Infrared Thermometer: Measures temperature without contact.
- Laboratory Thermometer: Used in experiments to measure precise temperatures.
- Maximum-Minimum Thermometer: Records the highest and lowest temperatures in a day.
- Mercury Thermometer: Uses mercury to measure temperature changes.
- Bimetallic Strip Thermometer: Employs two different metals to measure temperature.
