Best Refrigerator Thermometer

However, as you may already know, different foods have different temperature requirements. Some will be okay at cold temperatures while others do best in much colder temperatures.

Unfortunately, most refrigerators don’t have a clear way of showing the exact temperatures. What you get are some basic numbers such as 1.2,3,4, 5 or descriptions like cold, very cold, low, and high, etc.

This doesn’t exactly tell you what the interior temperature is. Fortunately, you can invest in a thermometer. And in this review, we will show you the best refrigerator thermometers on the market.

A refrigerator thermometer is especially useful if your fridge has only a dial thermostat. You can also use it to check that temperatures are still safe on a model with a built-in thermometer.

Refrigerator Thermometer

A refrigerator thermometer is a device used to measure the temperature inside a refrigerator or freezer. It is typically a small, battery-operated thermometer with a digital display that can be placed inside the refrigerator or freezer to monitor the temperature.

Refrigerator thermometers are useful for ensuring that food is being stored at safe temperatures to prevent the growth of harmful bacteria. The recommended temperature range for a refrigerator is between 35°F and 38°F (1.7°C to 3.3°C), while the recommended temperature range for a freezer is between 0°F and -5°F (-17.8°C to -20.6°C).

By using a refrigerator thermometer, you can check the temperature regularly and adjust the settings of your refrigerator or freezer as needed to ensure that your food stays fresh and safe to eat.

The Best Refrigerator Thermometer in 2023

A refrigerator thermometer can be an inexpensive way to save real money. If your refrigerator is too warm, food will spoil; if it’s too cold, you’re paying for more electricity than you need.

You should keep your refrigerator at no higher than 40° F and the freezer at 0° F, according to the United States Department of Agriculture.

The threat of food-borne illnesses is another concern with an improperly chilled refrigerator. Microorganisms capable of causing sickness to grow very slowly below 40°F. But they rapidly increase between 40° and 140°F.

A refrigerator thermometer is especially useful if your fridge has only a dial thermostat. You can also use it to check that temperatures are still safe on a model with a built-in thermometer.

And during a power failure, a thermometer is indispensable. If you’ve been without power for an extended period, you can use the thermometer to check that temperatures are still safe.

Find the Best Refrigerator Thermometer

We test, evaluate, and compare the latest refrigerator thermometers for measurement accuracy and readability. 

How We Test the Chill Factor

We recently tested three samples of five different thermometers for accuracy, readability, and stability (how quickly the thermometers responded to temperature changes). A thermometer that reacts too quickly to the warm air that enters a refrigerator when the door is opened can give you a misleading reading.

Making it harder to maintain your refrigerator at the proper temperature. To test for accuracy, we took five readings with each of the 15 thermometers and compared them with readings from a calibrated thermometer. The readings were averaged and scored.

An average of less than 1° F scored excellent, while a difference of 1 degree to 2 degrees scored very good.

All of the thermometers did a very good to excellent job of measuring the temperature, but they were prone to fogging, making them difficult to read. 

The Best Refrigerator Thermometer Reviews for 2024

Refrigerator and freezer thermometers are specially designed to provide accuracy at cold temperatures. For safety, it is important to verify the temperature of refrigerators and freezers. Refrigerators should maintain a temperature of no higher than 40 °F.

Frozen food will hold its top quality for the longest possible time when the freezer maintains 0 °F. Most refrigerators and freezers can be easily adjusted to run colder or warmer. The temperature control is usually accessible in the refrigerator part of the appliance. Check the owner’s manual for specific details on adjusting the temperature. An adjustment period is often required when changing the temperature.

What To Look Out For

Search for the best refrigerator thermometers, and you’ll get all kinds of products. But the truth is that not all products will be reliable. The numbers may be a little small, the lens/ dial may become fuzzy or cloudy, or it may start rusting or corroding.

You also don’t want something that isn’t food-safe since it may contaminate the food. The following are some of the things you should focus on when looking for an item:

Temperature Range

You must look for the range of temperature the thermometer handles. Nobody wants a unit that can’t handle the very cold temperatures. A good piece will have a wide range and will cater to even the extreme temperatures.

In addition, it will display in both Celsius and Fahrenheit either at the same time or has a button that allows you to change it. The markings will also be easy to understand and this especially applies to the analog type. For instance, it will have a 1-degree interval. Generally, digital types are much easier to read.

Safety and Hygiene

You should pay attention to the safety and hygiene of the gadget. The last thing you can imagine is the food being contaminated or spoilt because some paint or materials flaked off and fell on the food.

You also don’t want a rusty or corroded device hanging inside the refrigerator, do you? Always make certain that it is made from food-safe materials. Stainless and ABS plastic are among the common options. A good product is resistant to corrosion, rust, flaking, chipping, and more.

Also vital is making certain it doesn’t have sharp edges, crevices, jagged edges, or corners since this can be a good hideout for germs, dirt, bacteria, and more.

Ease of Placement

The best refrigerator thermometers will be very easy to place. They allow you to place them on a flat surface or hang them by a rack wire. Also, they will be lightweight so as not to add any stress on the select point.

Moving the unit will also be easy, just like placing it inside the unit. It will be made from tough materials that will handle the use, misuse, cold temperatures, food, and much more.

It will have a large and clear dial, the numbers will be bold and visible, and it will also have some colouring in different sections (analogue) for easy understanding. In the case of the digital type, it will feature a backlit display. You’ll also find some types with an audible alarm that alerts you when a certain temperature is reached.


Imagine the thermometer indicating -4, yet the true temperature is +2. You will place food believing it’s safe, but it will not. This may lead to spoiling and leading to waste.

A good piece will be very accurate and will have a very small margin of error to ensure you get the right temperature. Most top picks will have +/- 2 degrees Fahrenheit and this is good enough for most needs. They also will come ready to use and won’t require any kind of calibration. Besides, the battery will have a long lifespan.

A. Your refrigerator temperature should be 40 F or less, and your freezer should be 0 F or less. The best place to put a thermometer is in the warmest spot which would be near the door, not tucked away in the back. A glance at this daily to be sure it is maintaining a cold temperature.

A. Fridge thermometers can give insight into the relative safety of fridges and freezers in the home, as well as throughout commercial food chain systems, over time. They measure whether constant and ideal temperatures are maintained.

Q. How do I know if my fridge is cold enough without a thermometer?

A. You can put a container of water in the fridge to check the temperature. After a couple of hours, you will want to take a look at the container of water. You will want to look for condensation. If the condensation appears quickly that means that the water is very cold.

Q. What is an acceptable refrigerator temperature?

Q. Why is food freezing in my refrigerator?

A. If food in the bottom of the refrigerator is freezing, this could be caused by a refrigerator not having enough food to absorb the cold air. If food in the door is freezing, move the door bins up or down so they are one notch away from freezer vents. The fresh food control should be at the normal setting of 5.
