This top-rated forehead thermometer is on sale for just $21

The ReliefCare Infrared Forehead Thermometer is an FDA and CE-approved device that accurately measures your temperature and warns you when you’re having a fever.

Winter is prime time for colds and the flu to breed, but this winter has been particularly dangerous since an unprecedented amount of COVID cases are hitting hospital doors. COVID shares many symptoms with the flu and common cold, with one noteworthy commonality being a high fever.

When you’re in for a fever, you won’t spot it right away, but a thermometer can easily identify it before it gets serious. If you have the sneaking suspicion that you’ve been exposed to a fever-causing disease, COVID or otherwise, using a thermometer can confirm your suspicions. Luckily, thermometers aren’t expensive these days. In fact, this thermometer from ReliefCare only costs $20.99.

This Infrared Forehead Thermometer features dual measurement modes. You can get accurate temperature readings by placing the probe cover on your forehead. Removing the cover allows you to measure temperatures in your ears. The thermometer records this measurement and displays it on a mini LCD screen. The screen is backlit green if you’re within a healthy temperature range, but it’ll shine yellow or red if you’re experiencing a fever.

The ReliefCare thermometer can also save your temperatures so you can keep track of your progress over time. It’s not strictly limited to personal temperatures either. Using Ambient Mode, the thermometer can measure the temperature of a room, food, bathwater, and even a bottle of baby formula. Finally, the ReliefCare is FDA and CE-approved, making it a trustworthy option if you want to monitor your health and that of your loved ones.

The ReliefCare Infrared Forehead Thermometer currently has 4.3 out of 5 stars on Amazon, but it’s even cheaper on the Popular Science shop. Normally $29, this thermometer is on sale for just $20.99, or 30 percent off.
