For this reason, your top priority when purchasing a thermometer should be finding one that’s accurate and provides consistent readings. It should also be fast-acting—especially for kids and toddlers—and easy to clean if inserted into the mouth or rectum. Select designs also color code readings to indicate a fever (which is a temperature higher than 99.5 degrees Fahrenheit in adults, according to the National Health Institute) or use advanced infrared technology to get a no-contact reading.
Additionally, it’s important to purchase a thermometer based on your desired purpose. If you plan to use the thermometer on a newborn, it’s better to choose options that consistently monitor the infant or can be inserted into the rectum. Anyone planning to use a thermometer for fertility planning needs one that offers the most precise readings. Luckily, there are plenty of top-rated thermometers available for every situation.
