If you worry about the safety of food, then you’ll find the best refrigerator thermometer worth reading. Truth is that the refrigerator, or fridge if you prefer, has become a necessary have in the modern world. You’ll find it in almost every home, kitchen restaurant, hotel, bar, and catering unit and in many other places. It helps to keep food fresh and also extends its shelf life.
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 in 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.
What is 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 Bottom Line
The USDA offers helpful tips for determining whether food is safe after a power failure. And when you’re looking to replace your refrigerator, read our refrigerator buying guide.

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.
