An electronic thermometer is a modern medical device used to measure a person’s body temperature. Compared to traditional mercury thermometers, electronic thermometers have more advantages, such as high accuracy, ease of use, and high safety.
The following are the main features and working principles of electronic thermometers:

1. Accuracy and fast measurement: Electronic thermometers measure body temperature through electronic sensors, and their accuracy is higher than that of traditional mercury thermometers. They can usually measure body temperature quickly within tens of seconds, reducing waiting time and inconvenience.
2. Digital display: Electronic thermometers usually have a digital display screen that intuitively displays the measured temperature value, which is convenient for users to read and record.
3. Safety: Compared with traditional mercury thermometers, electronic thermometers use electronic components and plastic casings to avoid possible contamination and harm caused by breakage or leakage.
4. Versatility and portability: Some electronic thermometers have additional functions, such as automatic shutdown, memory function (recording previous measurements), sound prompts, etc., which increase the convenience of use and user experience. They are also often lightweight and easy to carry and store.
5. Different types: There are many types of electronic thermometers, including oral, axillary, ear and forehead temperatures. Each type has its applicable measurement scenarios and methods.

In medical and daily life, electronic thermometers have become a common tool for measuring body temperature. They are widely used in hospitals, homes, schools and workplaces to help people monitor their health status in real time and take necessary medical measures in a timely manner.
