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.

Pros
  • Slim and compact profile
  • Very accurate (±2°F / ±1°C)

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.

How We Decided

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.

Best Refrigerator Thermometer Buyer’s Guide

The Most Important Features to Consider

  1. Accuracy
    Our preference is for refrigerator thermometer accuracy to within ±2°F / ±1°C, which we feel is an acceptable variance before noticing a drastic disconnect between actual vs. imagined thermometer in the quality of your food. Most of our recommended picks operate within a ±4°F range, which is serviceable. No need to be adjusting the temperature here with odd calibrations.
  2. Digital vs. Analog
    Digital refrigerator thermometers carry a wider range of features for refrigerators and freezers, such as recent high and low readings for a better gauge of your refrigerator’s performance. Large LCD screens are also a pleasure to read. However, analog refrigerator thermometers have good color representation and bright red pointers that are just as readable. Choosing either is mainly a matter of preference.
  3. Construction
    Look for food-safe refrigerator thermometers that are encased in stainless steel or hard plastic to withstand those bumps in the refrigerator. Kudos for refrigerator thermometers that have stands or integrated hooks for easy hanging.
  4. Battery vs. Non-Battery
    Refrigerator thermometers batteries need to be replaced every three to six months. Keep that in mind when it comes to overall cost and convenience.

Refrigerator Thermometer FAQs

Are fridge thermometers accurate?

Yes, all of our recommended picks are pretty accurate thermometer. We consider good accuracy to be within ±4°F range, preferably in the ±1°F to ±2°F range.

Where should I put my fridge thermometer?

We highly recommend hanging it from the middle shelf, where the inner refrigerator temperature is most representative of the actual temperature. Placing it too close to the door could cause it to dislodge if it is opened with heavy force.

How do I know if my fridge is cold enough?

A quality refrigerator thermometer is the best way to tell if your refrigerator is cold enough. Refrigerators should not go higher than 40 degrees. Freezer temperature ranges anywhere from 0°F to -20°F. Many of our recommended picks have a colorful visual guide that shows what levels are acceptable and which ones are not.

At what temperature does food spoil in the refrigerator?

Any temperature above 40°F will cause perishable foods to spoil quickly. That is why it is very important to invest in a quality refrigerator thermometer if no built-in temperature display for the freezer and /or refrigerator is available.

What other refrigerator thermometer brands do you recommend?

Although they did not make our list, we really like the Wrenwane Digital Refrigerator Thermometer and the Taylor Commercial 1448 Refrigerator Thermometer. The Wrenwane is a no-frills device with decent accuracy (±4°F range) and a large digital LCD screen for easy readings.
