Thermometers

What's behind our thermometer Ratings?

Experts at our National Testing and Research Center tested 10 models in thermometers to see which ones perform best.
We look for:
  • Overall score
    Overall score is based predominantly on accuracy and repeatability, and to a lesser extent, on features, ease-of-use, and comfort.
  • Accuracy
    Accuracy is each model's performance compared to that of a medical grade thermometer. Readings were taken on adults without fever.
  • Repeatability
    Repeatability is the variation of each model's successive temperature readings. Readings were taken on adults without fever.
  • Features
    The Features score is a combination of objectively measured and observed attributes for accessories and operational performance.

Recommended thermometers

Recommended thermometers are standout choices with high scores. They include CR Best Buys, which offer exceptional value. When narrowing your choices, weigh features, price, and attributes that matter to you.
For your baby's first thermometer, go with an inexpensive digital model. Look for an LCD display that's easy to read and a start button that's easy to press. But don't be swayed by digital thermometers that claim to take a reading in an instant. A reading in 20 to 60 seconds is quick enough. If you're looking for information about thermometers, Consumer Reports is your best resource. Consumer Reports’ thermometer reviews will give you honest buying advice that you can trust. Use our thermometer buying guide to discover which features are most important to consider. We also provide unbiased Ratings and thermometer reviews to help you choose the best thermometer for your needs.
