Main Types of Fever Thermometers for Adults


We can divide the types of thermometers into two categories, namely, digital and infrared. Digital thermometers can read temperatures from the rectal, oral, or armpit. When it comes to response speed, digital thermometers are quite slow. Nevertheless, they are precise, affordable, and work for all age groups.

In contrast, infrared thermometers measure the surface body temperature, usually through the ear or forehead. They have a faster response rate and come with several features. Hence, they are quite expensive in comparison to their digital counterparts.

Fever Thermometers Buying Guide


Buying the right thermometer is essential if you want to get precise readings. Apart from the accuracy, here are some necessary things that you should consider when looking for the best thermometer for adults:

Response Speed
Whether you want fast or slow response speed is a matter of personal preference. But you should note that the response speed of a thermometer can range from a few seconds to a minute. If you want quick results, consider products with faster reading speed.

Memory Function
Some advanced thermometers come with this feature for storing previous temperature readings. You can use this information for future reference, which will help you determine whether the temperature has increased or decreased.

Besides, some products allow you to store more than 20 temperature readings at a time.

Measurement Unit
Generally, a thermometer measures your body temperature either in Fahrenheit or Celsius. However, some products come with both the measurement units.

Backlit Display
If you want to read the temperature results clearly, then you should consider a thermometer with a substantial screen. Additionally, choosing a screen with a backlit feature will allow you to use it in the dark or dim light environments.

Fever Alert Indication
Some thermometers come with this feature to notify you if the temperature is higher than average. The indication can vary from a visual alert to an audible beep. You can also find some advanced thermometers that have both alarms.

Long Battery Life
One of the essential things to consider when buying a thermometer relates to battery life. Some products use AA or AAA batteries, while others come with cell batteries. Whatever the option is, you should ensure that your thermometer has great battery life. Besides, we recommend at least having an additional pair of batteries for an emergency.

Auto-Shut Off
This feature will prolong the battery life, especially when you forget to turn off the device. As such, you should look for a thermometer that automatically turns off after a few seconds when you do not use it.
