If you’re concerned about food safety, you’ll find the best refrigerator thermometer worth reading. The refrigerator, or fridge if you prefer, has become a necessary item in the modern world.
You’ll find it in almost every home, kitchen, restaurant, hotel, bar, catering unit, and other establishments. It helps keep food fresh and extends its shelf life.
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 clearly show the exact temperatures. You get basic numbers such as 1.2, 1.3, 3.4, or 5, or descriptions like cold, very cold, low, and high.
This doesn’t exactly tell you what the interior temperature is. Fortunately, you can invest in a thermometer. This review 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 measures 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 help ensure that food is 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).
Using a refrigerator thermometer, you can check the temperature regularly and adjust the settings of your refrigerator or freezer to ensure that your food stays fresh and safe to eat.
The Best Refrigerator Thermometer in 2025
A refrigerator thermometer can be an inexpensive way to save money. If your refrigerator is too warm, food will spoil, and if it’s too cold, you’ll be paying for more electricity than you need.
According to the United States Department of Agriculture, you should keep your refrigerator at no higher than 40°F and the freezer at 0°F.
Another concern with an improperly chilled refrigerator is the threat of foodborne illnesses. Microorganisms capable of causing sickness grow very slowly below 40°F but rapidly increase between 40°F 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.
A thermometer is indispensable during a power failure. If you’ve been without power for an extended period, you can use it 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.
This makes it more challenging 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 ° F to 2 ° F scored very good.
The thermometers performed very well in measuring the temperature, but were prone to fogging, making them difficult to read.
The Best Refrigerator Thermometer Reviews for 2025
Refrigerator and freezer thermometers are specially designed to provide accuracy at cold temperatures. Verifying the temperature of refrigerators and freezers is crucial for safety. Refrigerators should maintain a temperature of no higher than 40°F.
Frozen food will hold its top quality for the longest 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 find a range of products. But the truth is that not all products will be reliable. The numbers may be 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 temperatures the thermometer handles. Nobody wants a unit that can’t handle very cold temperatures. A good piece will have a wide range and will cater to even extreme temperatures.
In addition, it will display in both Celsius and Fahrenheit, either simultaneously or with 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 gadget’s safety and hygiene. The last thing you can imagine is the food being contaminated or spoiled because some paint or materials flaked off and fell on it.
You also don’t want a rusty or corroded device hanging inside the refrigerator, do you? Always make sure that it is made from food-safe materials. Stainless steel and ABS plastic are among the standard options. A good product is resistant to corrosion, rust, flaking, chipping, etc.
Also vital is ensuring it doesn’t have sharp edges, crevices, jagged edges, or corners, as these can be good hideouts for germs, dirt, bacteria, and more.
Ease of Placement
The best refrigerator thermometers are very easy to place. They can be placed flat or hung on a wire rack. They will also be lightweight to avoid stressing the selected point.
Moving the unit will also be easy, just like placing it inside the unit. It will be made from rigid materials that can withstand use, misuse, cold temperatures, and food.
Easy Reading
The goal of investing in a thermometer is to make life easier and more convenient. Consumers want to spend the least amount of effort and time reading the temperature. A top pick will have a clear, easy-to-read display.
It will have a large and clear dial, bold and visible numbers, and some colouring in different sections (analogue) for easy understanding. The digital type will feature a backlit display. You’ll also find some types with an audible alarm that alerts you when a specific temperature is reached.
Accuracy
Imagine the thermometer indicating -4, yet the proper temperature is +2. You will place food believing it’s safe, but it will not be. This may lead to spoiling and waste.
A good piece will be very accurate, with a very small margin of error, to ensure you get the right temperature. Most top picks will have a temperature range of +/—2 degrees Fahrenheit, which is good enough for most needs. They will also come ready to use and won’t require any calibration. Besides, the battery will have a long lifespan.
(FAQs)
Q. Where is the best place to put a thermometer in a fridge?
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 ensures it is maintaining a cold temperature.
Q. Can you take your temperature with a fridge thermometer?
A. Since a few refrigerator controls show actual temperatures. An inexpensive freestanding appliance thermometer will allow you to monitor the temperature and adjust the refrigerator and/or freezer settings if necessary.
Q. Why is a fridge thermometer recommended?
A. Fridge thermometers can give insight into the relative safety of fridges and freezers in the home and 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 water container in the fridge to check the temperature. After a couple of hours, you will want to 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?
A. Keep your appliances at the proper temperatures. Keep the refrigerator temperature at or below 40° F (4° C). The freezer temperature should be 0° F (-18° C). Check temperatures periodically.
Q. What is the coldest temperature in a refrigerator?
A. In the coldest setting, the temperature is approximately 34 degrees in FF and -5 degrees in FZ. In the middle (colder) setting, the temperature is approximately 37 degrees in FF and 0 degrees in FZ. At the warmest (coldest) setting, the temperature is approximately 40 degrees in FF and 5 degrees in FZ.
Q. Is 5 degrees OK for a fridge?
A. Use a fridge thermometer to check the temperature of your fridge regularly. The coldest part of the fridge should be between 0 degrees Celsius and 5 degrees Celsius (32 degrees Fahrenheit and 41 degrees Fahrenheit).
Q. Will food spoil at 50 degrees in the refrigerator?
A. Food starts to spoil when the temperature rises above 40 degrees. After food warms to that temperature, you have just two hours to either return it to cold conditions or cook it. In the fridge, produce will survive most power failures, but dairy products should be discarded if they smell or taste sour.
Q. Why is my fridge temperature too high?
A. There’s a chance that your temperature sensor is broken or not correctly set. Or that the defrost timer is broken, or the vent fan between the compartments. There might be something wrong with your compressor, such as a coolant leak, or it might just be a loose wire somewhere along the way.
Q. Why is food freezing in my refrigerator?
A. If the food at the bottom of the refrigerator is freezing, this could be caused by a refrigerator not having enough space to absorb the cold air. If the food in the door is freezing, move the door bins up or down so they are one notch away from the freezer vents. The fresh food control should be at the typical setting of 5.
