10 Best Freezer Thermometer in 2022 [Reviews & Buying Guide]

It is all well and good owning a refrigerator until it works well. If you own a freezer that doesn’t maintain optimal temperatures inside, chances are that you will be left with rotten food and a bad-smelling fridge. That is the last thing anyone wants to experience, to put it lightly. This is where a freezer thermometer comes into play. Not only do they help you gauge the internal temperatures of the fridge, but they also help prevent any kind of extreme temperature fluctuations in the freezer.

If you are witnessing extreme and rapid food spoilage even after keeping your food in the refrigerator, chances are that the internal temperature of the refrigerator is under 40 degrees Fahrenheit. That said, simply place the thermometer in the fridge won’t give you accurate readings. It is always better if you place the thermometer between frozen foods or directly plunge it into a tub of ice cream to keep a check.

Once you have placed the thermometer, keep an eye out for the readings every few hours to check if there are any drastic changes. Ideally, the thermometer should always point at 0 degrees Fahrenheit, since that is the maximum temperature for the frozen foods. If your fridge doesn’t manage to keep the food at the right temperature, chances are that it won’t be safe to consume in the long run.

Now that you know about the significance of the freezer thermometer, you must know which products are good and which ones are a hard pass or extremely overhyped. Here, we have sorted out a list of the best freezer thermometer that you can buy for personal use.

Buying Guide 

Not every person on this planet is familiar with the concept of a fridge or freezer thermometer, so it isn’t surprising that many of the users are often confused about their purchase before buying it. There are a few key factors that you need to keep in mind before buying a freezer thermometer to ensure enhanced durability like no other in the market.

  • Temperature range

The first and likely the most important factor to check is the reading temperature range. Invest in the ones that cover from -4°F to 140°F, because that is the optimal range. Anything less or more should be concerning. So, instead of picking out a random option, consider looking at the range without fail.

  • Material

Given that you are going to put the thermometer inside the fridge or freezer, you must find a thermometer that is constructed with durable quality material. Stainless steel or heavy-duty plastic with proper waterproof features are considered the best ones.

  • Display/Readings

The last thing you want in a thermometer is to have a smaller display that makes you squint your eyes small to get accurate readings. If you struggle with vision-related issues, it is always best that you buy the thermometers with oversized displays and larger texts for taking easier readings.

  • Price range

The last factor to consider is the price range. Most of the freezer thermometers available in the market are priced under $15, which means that they aren’t all that expensive. That said, there are a few high-end options too. However, don’t consider spending more than $30 on the thermometers.


1. Where should I place my freezer thermometer?

If this is your first time buying or using a freezer thermometer, it is always best that you place them near the door instead of placing them in the back.

2. Are freezer thermometers worth buying?

Yes, if you are witnessing a lot of food spoilage despite being in the fridge, having a freezer thermometer helps you assess the problem. It helps you know if the fridge isn’t functioning optimally or if there’s something else. You can act accordingly, including, adjust the temperature (increase or decrease it) and even know when to defrost your fridge.

3. What is the ideal freezer thermometer reading?

Generally, the freezer should be at 0 degrees Fahrenheit, especially if you have frozen foods inside your freezer. Anything more than that will most likely result in spoilage of the products you keep inside.


With so many different types of freezer thermometers available in the market, choosing the right one for your refrigerator can be a little challenging.
