Backlighting
The backlit display and clear and easy-to-read numbers are useful for taking body temperature at night. Many people didn't pay attention to this function when they bought it, and they found it inconvenient when they were sleepy and confused to measure their body temperature and couldn't see clearly.
Prompt after measurement
A voice-activated or signal indicator-type prompt function indicates that the current temperature measurement has been completed.
Fever warning
Some models will sound an alarm when the measured temperature exceeds 38°C. Others use visual fever warnings, red, yellow, and green like traffic lights to represent the temperature level.
Temperature memory
Some high-end models can record multiple sets of body temperature data. This function can save you the trouble of recording yourself.
Automatic shutdown
In order to save battery life, some clinical thermometers are equipped with an automatic shutdown function.
Celsius and Fahrenheit switch
You can switch the body temperature back and forth between degrees Celsius and Fahrenheit. If you need this, you can consider it.
