Lämpötilalaitteet
Lämpötilalaitteet, commonly known as thermometers, are instruments used to measure temperature. They operate based on the principle that physical properties of matter change with temperature. The most common type is the liquid-in-glass thermometer, which utilizes the thermal expansion of a liquid, typically mercury or colored alcohol, within a sealed glass tube. As the temperature rises, the liquid expands and rises in the calibrated tube, indicating the temperature.
Another widely used type is the digital thermometer, which often employs thermistors or thermocouples. Thermistors are
