The liquid commonly used in clinical thermometers is mercury, known for its uniform expansion with temperature changes. However, due to safety concerns, many modern thermometers now use alcohol-based liquids, often colored for better visibility.

Clinical thermometers traditionally use mercury as the liquid, valued for its consistent expansion with temperature changes, allowing for precise measurements. However, due to safety concerns related to mercury’s toxicity, many modern clinical thermometers utilize alcohol-based liquids instead. These alcohol thermometers are often colored, typically red or blue, to enhance visibility of the reading. Both types are effective, but the shift towards alcohol-based thermometers reflects a growing emphasis on safety and environmental considerations in medical practices.
