A digital thermometer measures your body temperature with an electronic sensor and shows the result on a small screen. It is faster and safer than an old mercury thermometer. In this article, you will learn how it works, how to use it, and what to look for when you buy one.
How Does a Digital Thermometer Work?
You can take a reading in different places, depending on the model:
- Orally: Place the tip under the tongue and close your mouth.
- Axillary (under the armpit): Place the tip in the armpit and hold your arm against your body.
- Rectally: Doctors often use this method for babies, and it gives the most accurate reading.
The thermometer beeps after a few seconds and shows your temperature. A reading of 38°C (100.4°F) or higher usually means a fever.
Benefits of a Digital Thermometer
- Accuracy: It gives a precise reading within seconds.
- Safety: It has no mercury, so it is safer for children.
- Ease of use: People of all ages can use it.
- Portability: It is small and easy to carry.
How to Choose the Right Digital Thermometer
- Speed: Some models give readings faster than others.
- Memory: Some models store earlier readings, which helps you track changes.
- Waterproof design: A waterproof model is easier to clean.
- Flexible tip: A flexible tip is more comfortable, especially for children.
Tips for Using It Safely
- Wait about 15 minutes after eating or drinking before you take an oral reading.
- Clean the tip with soap and water or rubbing alcohol after each use.
- Use a separate thermometer for rectal readings.
