Our Digital Thermometer Buying Guide

When you or a loved one is not feeling well, it’s important to have an accurate digital thermometer around so you can do a temperature check. Knowing whether someone has a fever can help you decide whether they need to go to the doctor or just need to lie down and rest for a day. With young children, high fevers can sometimes lead to more serious health issues, so it’s vital to know you can trust the reading on your digital thermometer.

A digital stick thermometer is best used orally, in the underarm or rectally. They either have a rigid or flexible tip, which affects the way they should be used. The tip senses the temperature which is then displayed numerically on an LCD screen. Another type of digital thermometer is the infrared thermometer. They are designed to measure the heat that your body emits. They work in a short amount of time, typically between one to three seconds. Some infrared thermometers are to be used on the forehead, while others are designed to go in the ear. There are also non-contact infrared thermometers, which detect your body temperature from a few inches away. These are typically used on the forehead as well.

One of the most important features to look for on your digital thermometer is the display feature. It should be large and easy to read the numbers without any confusion. If you will be taking temperatures at night or in a dark room, then having a backlit display is key so you don’t have to turn on the light and disrupt your patient. Having an audible sound that tells you when the thermometer has secured a reading is also important so that you don’t remove it too soon. Having the option to turn off the beep is also helpful if you don’t want to wake someone who is sleeping.

DWYM Fun Fact

Thermoscopes were the predecessors to thermometers. The first one was developed in 1593 by Galeleo Galilei. This kind of temperature-measuring device showed changes in temperature but did not show any numerical values related to the change. A thermoscope was a glass vial that had water and glass bulbs. As the water rose and fell with the changes in temperature, the glass bulbs rose and fell, too, showing a visibly perceptible change. Later on, thermoscopes were filled with alcohol instead of water, and some had numerical scales. While these rudimentary inventions were not highly accurate, they provided the basic design for the modern thermometer.

The Digital Thermometer Tips and Advice

  • Some digital thermometers have age-specific features, which is handy to use if you have young children. Since high fevers can be particularly dangerous for babies and little kids, using this feature can provide you with custom alerts based on your child’s age.
  • Having a quick response time is a feature many people look for, especially if the thermometer is for children. Digital stick thermometers typically take between 10 to 90 seconds to read a temperature, while infrared thermometers can provide a reading within one to three seconds.
  • If you want to track the progression of a fever over time, then look for a digital thermometer that has a memory capacity. Some thermometers store the last reading while others can store multiple readings. This is a good way to check to see if your patient is getting better or worse over time and decide on your next steps.
  • Some digital thermometers come with a fever alert, where the display shows a different color or makes a different sound if the temperature is elevated. This is particularly helpful when you don’t remember what temperature constitutes a fever.
  • For children under 3 years old, the most accurate temperature reading will be rectally. For older kids, you can use an oral or armpit reading. For adults, using an oral or infrared reading will give you accurate results.
  • If you plan to use a digital stick thermometer rectally, it’s best to get two thermometers. You can dedicate one to rectal use and use the other in the armpit or mouth. Be sure to label each thermometer with its use so you don’t accidentally mix them up.
