Award: TOP PICK
WHY WE LIKE IT: This refrigerator thermometer comes with a large analog display (6″ tall) and is battery-free, a great choice for people who would prefer not to swap out batteries every couple of months.
This refrigerator thermometer is built very sturdily with a stainless steel base and a shatterproof lens. It is pretty rigid, more than capable of standing the occasional drop. A large dial with a brightly marked needle and bold letters makes it very easy to read. Kudos for a hanging tab that allows us to be suspended on any rack.
This refrigerator thermometer’s temperature range runs from -20 to 80°F, displaying both Fahrenheit and Celsius readings for any fridge and freezer. While testing, we determined findings were accurate to within -/+ 2 degrees, which is very respectable. A mechanical thermometer also eliminates the need for a battery, so it requires much less maintenance over time. Compare this fridge with our guide to the best french door refrigerator to make sure you’re making the right choice.
Award: HONORABLE MENTION
WHY WE LIKE IT: This large refrigerator thermometer comes with a large 3″ analog dial, working great for people with limited visibility, with acceptable temperature ranges marked right on said dial.
This refrigerator thermometer’s temperature range reads within -20 to 80 degrees Fahrenheit, with tested accuracy levels to within -/+ 3°F,- very commendable in our book. Markings even depict ‘safe’ and ‘unsafe’ temperature ranges (e.g. 40 degrees to 80°F are marked ‘Danger” and 0 to -20°F is marked as ‘Freezer’ level.
Our favorite feature with this refrigerator thermometer is its extra-large proportions with a 3-inch dial, durable glass lens, and bright red pointer for easy reading. Plus, a small hang tab and sturdy steel base makes it easy to hang or stand on a fridge wire rack or bottom shelf. Just be prepared to potentially move it on occasion based on your refrigerator’s fill level. If you’re still not sold by this fridge, try starting with our guide to the best refrigerator brands.
Award: BEST QUALITY
WHY WE LIKE IT: This refrigerator thermometer comes with large LCD screens, high accuracy (/±2°F) and comes in a two-pack, making it a great choice for people who own multiple refrigerators.
We love how accurate this Unigear refrigerator thermometer is, with accuracy to within ±2°F. In addition to the current reading, it also tracks recent high and low temperatures to better manage your cooling. A large LCD screen presents a clean display and it can either stand or hang on a hook on a fridge shelf for better visibility.
Our only knock is this refrigerator thermometer needs a small 3-volt lithium battery which needs to be replaced every three to six months. However, this refrigerator thermometer more than makes up for it with recent High and Low-temperature readings for users to get a better sense of how temperatures change over time. This fridge is definitely among the best refrigerators available on the market.
Award: MOST DURABLE
WHY WE LIKE IT: This refrigerator thermometer comes with a sturdy stainless steel construction and comes in a two-pack, good for people who want to keep an extra one handy or take on a trip.
This freezer thermometer does a great job with temperature readings. Our testing revealed accuracy to within ±4°F, which is acceptable. A large dial displays bold temperature numbers with a bright red pointer and graphics for temperature range (OK Freeze, Freezing, Refrigerator, and Warm), which provides a nice visual guide on what temperature is acceptable depending on its placement in a freezer or main refrigerator shelf.
We love this refrigerator thermometers construction, made of rust-resistant stainless steel. A wide base stand and small hook also allow it to stand or hang on a refrigerator shelf, so it can be as visible as you would like it to be. All in all, we were very impressed with this refrigerator thermometer’s overall build quality. While you’re at it, you might also want to look at our guide to the best refrigerator water filter.

Award: EASIEST TO READ
WHY WE LIKE IT: This refrigerator thermometer comes with a jumbo-sized dial and a wide steel base, making it perfect for the vision impaired or the elderly.
This refrigerator thermometer is an all-around workhorse. A large, easy-to-read dial displays the temperature from -20 to 80 °F with a well-labeled scale for safe and unsafe temperatures (e.g. OK Freeze’ Freezing, Refrigerator, and Warm ranges. We love this, as it provides a quick visual on refrigerator safety.
While testing we observed respectable accuracy of ±4°F. Our only knock is that it is not as accurate as our leading picks (±1°F to ±2°F range), so food may need a little extra visual inspection every now and then. If you are looking for a no-frills and inexpensive refrigerator thermometer with a degrees Celsius option, this is an excellent choice.
Award: BEST ON A BUDGET
WHY WE LIKE IT: This refrigerator thermometer comes in an ultra-slim profile (4.25″ by 0.625″), making it a great choice for small fridges.
Our favorite feature with this refrigerator thermometer is its slim profile. At only 0.625″ long, it takes up very little space. A single vertical glass tube is capped on both ends with polyethylene end caps, good enough to withstand an occasional drop.
Accuracy with this refrigerator thermometer is on point, working to within ±2°F / ±1°C. Consider this a no-frills refrigerator thermometer for readings only, lacking some of the features of others including stands, large circular dials with color guides, LCD screens, and recent High and Low-temperature readings for a better read on refrigerator settings over time. We love how easy it is to check the temperature with this unit.
In determining the best refrigerator thermometer to buy, we explored accuracy, digital vs. analog, construction, and battery vs non-battery.
Accuracy is the most important feature. We recommend refrigerator thermometers with an accuracy rate of ±2°F / ±1°C. This means actual real-world temperature only varies within that range for a truer reading. Second-grade refrigerator thermometers carry wider variances (e.g. ±4°F / ±1°C), which can be made up with other features such as color scales, integrated hooks, and LCD screens.
We evaluated digital vs. analog refrigerator thermometers. Digital refrigerator thermometers carry large LCD screens with digitized numbers – crisp and easy to read. Analog refrigerator thermometers consist of larger dials with magnetized pointers. Arguably, analog provides a better visual representation, as some include visuals for safe temperature ranges based on freezing, regular refrigerator, and warm temperatures.
One important distinction is the use of high and low recent temperatures. Digital refrigerator thermometers have a broader range of features such as this one. Choosing either is mainly a matter of preference and aesthetics.
Construction is a key consideration. We like refrigerator thermometers encased in stainless steel or hard plastic to better withstand regular wear and tear. These can even be used as outdoor thermometers or room thermometers.
Lastly, we assessed refrigerator thermometers based on battery versus no battery. Some refrigerator thermometers need battery replacement every three to six months, which can be tough to manage over time.
