What are the 4 types of thermometer?

Answer 1

The four common types of thermometers are:

1. Mercury Thermometers: These use mercury in a glass tube that expands or contracts with temperature changes.
2. Digital Thermometers: These provide quick readings using electronic sensors and are often used for medical purposes.
3. Infrared Thermometers: These measure temperature from a distance by detecting infrared radiation emitted from an object, commonly used for skin temperature.
4. Bimetallic Thermometers: These consist of two different metals that expand at different rates, causing a dial to move and indicate the temperature, often used in industrial settings.
