Thermometer Buying Guide

When it comes to buying a thermometer, you want to make sure that you buy the best one possible. A model that’s not only easy-to-use and has the features you need it to have, but one that’s also extremely accurate. To help you find the best thermometer available, we included some of the things that you should look for when buying one of these models. To make things a bit easier, we will begin this guide with the best thermometer types according to age.

Best Thermometers By Age

Children 3-Years & Younger
Most doctors will agree that parents with children under the age of 3-years old should use a rectal thermometer for best results. Rectal thermometers are also officially recommended for children in this age range by the American Academy of Pediatrics or AAP. That’s because these thermometers are the most accurate and provide the best results. However, some parents like to take the child’s initial temperature with an armpit thermometer, which is one of the least accurate thermometers available, and if the temperature reading is 100-degrees Fahrenheit or higher, then double check the results using a rectal thermometer.

Children Above the Age of 3-Years Old
When children are 3-years of age or older, then parents have a few options available as far as thermometers are concerned. Parents can choose to use either an oral thermometer or an ear thermometer. Although most children older than 3-years old can tolerate an oral thermometer, some of them don’t cooperate during use, so ear thermometers have to be used. However, even these thermometers can present problems, especially if the child refuses to sit still, so some parents have begun to migrate to temporal artery thermometers instead. These are easy to use and provide the parent with a quick reading, but once again, if the temperature is high, then it may be necessary to recheck the temperature using a rectal thermometer.

Teenagers & Adults
Most teenagers and adults prefer not to use rectal thermometers to take their temperatures for obvious readings, but they do have a few options available to them. They can choose to use an armpit thermometer, but they should keep in mind that these thermometers are the least accurate. They can also choose to use ear thermometers, but these can also be difficult to get a good reading from because they have to be placed precisely in the ear, although most doctor’s offices prefer this method of obtaining a temperature. This leaves oral thermometers and infrared thermometers, both of which are good options for obtaining an accurate temperature.
