The 7 Best Fridge Thermometers

Best Overall

ThermoWorks Fridge/Freezer Thermometer

View On Thermoworks.com

Why we chose it: This highly-rated thermometer pulls double duty, since it has two probes that can be used to measure accurate temperatures on an easy-to-read LCD display in both the refrigerator and freezer.

We love that this fridge thermometer covers all of the bases—because it has two channels and two probes, it can be used simultaneously in both the refrigerator and the freezer. Simply insert one probe in the freezer and one in the fridge. You can also set high and low temperature limits so that the audible alarm will alert you to any changes—you don’t have to keep taking manual readings.

The thermometer also includes a convenient fold-out stand and magnetic rear-panel clips, so it’ll stay put wherever you place it. Plus, it has a very easy-to-read LCD display to ensure you get the temperature readings just right.

This fridge thermometer is proof that you don’t have to spend big bucks to get a reliable temperature gauge for your appliance. Sure, you won’t get extras like an LCD display or magnet to hold it in place, but you’ll get exactly what you need: an accurate thermometer. 

The small stainless steel thermometer reads between negative 20 and 80 degrees Fahrenheit—perfect for the vast majority of traditional refrigerators, mini-fridges, freezers, and even coolers (great to ensure your barbecue fare stays within a safe range). It also has a shatter-proof screen, so you won’t have to worry if it does accidentally tip over.

And as a big bonus, this model doesn’t require any batteries, so there will never be a lapse in readings.

Best Easy to Read

VOULOIR Fridge Thermometer

View On Amazon

Why We Chose It: This thermometer has a large, easy-to-read display and intuitive controls—all for a budget-friendly price.

The standout feature on this fridge thermometer is the 2.56-inch electronic LCD display that’s a cinch to read, even from a distance. And that’s not all the screen will tell you—the information on the screen simultaneously displays the maximum and minimum temperatures of the day as well as the current temperature (the bigger number). 

It’s easy to operate and toggle between modes, too. The thermometer has just three buttons (all on the back), so all you have to do is press on, off, or the button that shifts the mode from Celcius to Fahrenheit. Still, the unit has a wide temperature range that makes it perfectly suitable for both the fridge and the freezer—the temperature spans from negative 4 to 122 degrees Fahrenheit.

Best Multipurpose

AMIR Wireless Refrigerator Thermometer

View On Amazon

Why We Chose It: This smart thermometer works off of sensors you can use in both the fridge and freezer, then delivers the temperature on an easy-to-read LCD screen.

This thermometer (which is a new-and-improved version) has two sensors that allow you to monitor both the refrigerator and the freezer wirelessly at the same time. Simply stick the sensors where you want them (you can hang them, too!), and keep an eye on the temperature via the separate—and very large and easy to read—LCD display. The display unit can stand wherever you want it to, whether that’s on the table, tucked on a shelf, hung on the wall, or with a magnet on the refrigerator.

The display itself records minimum and maximum temperatures, historical temperature readings, and the current temperature. If anything’s amiss, both visual and audible alarms will alert you right away to minimize the chance of food spoilage.

But one of the best things about this thermometer is that you can use it outside of the kitchen, too. Use it to monitor the temperature of any space—like a baby’s nursery or the garage.

Best Magnetic

Taylor Pro Series Digital Fridge/Freezer Thermometer

Why We Chose It: The magnetic design ensures that this thermometer, which has a large digital display, is always in sight.

There’s a lot to love about a magnetic fridge thermometer: There’s no concern that your unit is going to tip over, making it harder to read. Plus, when you’re able to stick the unit onto the wall of your fridge, you conserve precious space. We love that this round device has that precious magnet, but also has a clip and a stand should you want to stash the device in one of the more traditional ways. 

No matter which way you choose to set up the thermometer, you’ll love how easy the display is to read. The temperature reading—a large digital number—is perfectly centered on the screen. But just in case there’s any confusion (maybe you don’t know exactly how cold the fridge or freezer should be), the device also displays a happy or sad face to indicate whether the temperature is in a safe zone or not.

Best Set

AcuRite Refrigerator Thermometer

Why We Chose It: This thermometer comes with two sensors—one for the fridge and one for the freezer—plus has an alarm, so you’ll know if the temperature on either goes out of range.

If you have multiple appliances to monitor, try this refrigerator thermometer, which includes two sensors—one for the refrigerator and one for the freezer. The sensors are wireless, so all you need to do is place them inside the unit. You can put the standalone display anywhere you can easily spot it—on the counter or a shelf, perhaps—but it’s magnetic and has a keyhole for hanging, so you could also mount it straight onto the refrigerator or the wall. 

The display is relatively large, too, so you can spot it from afar. Additionally, you can program alarms easily so that you’ll be notified when the temperature exceeds your desired maximum, reducing the chance that food spoils.
