What type of thermometer uses infrared technology to measure temperature?

• A. Glass thermometer
• B. Digital thermometer
• C. Tympanic thermometer
• D. Infrared thermometer

Answer: (D)

The infrared thermometer uses advanced infrared technology to measure temperature from a distance. It detects the infrared energy emitted by an object, such as the human body, and converts that energy into a temperature reading. This method allows for quick and non-invasive temperature assessment, making it particularly useful in clinical settings where speed and ease of use are important. Infrared thermometers can be used on the forehead or in other locations where traditional thermometers may be impractical or slower to use.

In contrast, other types of thermometers, like glass thermometers and digital thermometers, typically require contact with the body or another surface to accurately measure temperature, which can be less convenient in certain situations. Tympanic thermometers, while also providing quick readings, specifically measure temperature inside the ear and are therefore less versatile than infrared models.
