Best Fridge Thermometer UK

Most people would think that the only types of thermometers they need in their household are body and room thermometers. While those two are essential, especially for families with babies/young children, there are times when fridge freezer thermometers are required as well.

For example, certain medication can be kept only in specific temperatures (+/- 4 degrees Celsius). You can’t find such temperatures anywhere in the house in Summer. That’s why you need to know if it’s safe to store medication in your fridge.

Moreover, you could also use thermometers to see whether your fridge or freezer are functioning properly or not and to make sure you follow good food safety practices.

Luckily, we’re here to help you find the best refrigerator thermometer in the UK, with a curated list of the top products on the market. All you need to do is find the one you like and order it online – the best way of window shopping there is!

Best Fridge Thermometers

1. Suplong Digital Waterproof Refrigerator Thermometer with Easy-to-Read LCD Display

First on our list is this Suplong thermometer, claimed to be the simplest there is on the market. It comes with a wide temperature range, making it ideal as both a fridge freezer and room thermometer reading – namely, from as chilly as 20°C to as hot as 60°C.

The device features two buttons only, hence the simplest: an on/off and a temperature switch button, in case you’re more accustomed to Fahrenheit readings.

Among its top features, we must mention the thermometer’s big digits, magnetic back, as well as the hook that can be used for convenient hanging within the appliance. The big digits allow you to place it in the back of the fridge, for accurate readings, and to still be able to read it!

2. KitchenCraft Freezer/Fridge Thermometer with Min Max Temperature Guide

Next on our list, we have this vintage-looking thermometer. It is ideal for kitchens – or fridges – that come with bright silver as their dominant colour.

As you may have noticed, this is not a digital refrigerator and freezer thermometer. Instead, it has a classic dial and a pin that points to the temperature of the food. This feature makes this product extremely easy to read as you just have to follow the bright red needle!

The range goes as low as -30 degrees and as high as 30 degrees. Ideal for fridges, but not for rooms. Obviously, no batteries are required for this beauty!

3. Unigear Thermometer, Waterproof Refrigerator Freezer Thermometer

This digital fridge/freezer thermometer from Unigear comes with a robust build and a sturdy, professional look. It also comes with a one-hook-wonder, so to speak.

Namely, the thermometer’s hook is foldable, meaning that you can use it to place the product inside, turn it into a stand, or hide it completely on the back of the thermometer. This makes it perfect for hanging, simple freezer placement, and as a general room thermometer via its stand.

When it comes to range, it is from -20 Celsius up to 50 Celsius. On top of that, the LCD screen shows the maximum, minimum, and current temperature – all at the same time!

4. Thlevel 2x Digital LCD Thermometer Temperature Monitor with External Probe

This particular thermometer comes with a neat little feature that can make a lot of household activities much easier to handle. Of course, we’re talking about the external probe that you can use to measure the temperature of almost anything – within the range of -50 degrees and +100.

The device comes with a classy, black look and won’t interfere with the home décor even if you place it in your bedroom.

It’s safe to say that this is more than just a freezer and refrigerator thermometer: it can measure the room climate and indoor temperature, to name a few. This makes it a multi-purpose tool for the temperature freak!

5. WXJ13 4 Pack Refrigerator Freezer Thermometer Classic Series Large Dial

This is yet another classic/vintage-looking entry on our list – also in the count of 4! The pack features four silver thermometers that you can use in multiple fridges, or within the same fridge if you want extremely accurate fridge temperature readings.

The dial-and-needle thermometer has a range of -30 to 30 degrees Celsius. The colours red, light blue, and bright blue mark the three potential zones – warm, freezing, and “OK freeze”.

 Last but not least, this small thermometer can be either hung from a shelf or placed on one, thanks to its wide stand.

6. Salter Analogue Fridge Freezer Thermometer

If you have a modern fridge, with a dark silver finish, then this Salter thermometer might be more than just interesting for you.

As most other refrigerator thermometers, this one features with a steel body as well, for maximum durability. Moreover, since the product comes from a reputable brand with more than 200 years on the market, its quality is ensured!

The dial is quite large, with clearly marked big numbers (from -30 and up to 30 degrees Celsius), and with a long, bright red needle as well. On top of that, the glass display is equipped with a magnifying lens, making it incredibly easy to read temperatures on this thermometer.

7. ETI Digital Fridge or Freezer Thermometer with Internal Sensor and Max/Min

The next entry on our list comes with a couple of extra features that make up for its rather simple design/look, so to say. It comes with not one, but two sensors – an internal one and an external one, in the form of a probe.

However, the probe cable is quite short and will not be a nuisance.

Moving on, this is a thermometer with an alarm that has both high and low audio signals. As such, the product is perfect for people that have to change their settings regularly.

8. RUIJING Refrigerator Thermometer Measures Frozen Food Storage

This digital thermometer for fridge or freezer comes with a classic kitchen look. It has big, bold, easy-to-read numbers, as well as large buttons.

Speaking of buttons, there are four in total: one for displaying the minimum and maximum temperature, as well as the humidity, one for the indoor and outdoor and humidity detection modes, and one for setting up the alarm. The final button is located at the end of the thermometer and is used to switch between Celsius and Fahrenheit.

The product also comes equipped with a probe that comes in handy when measuring the outdoor humidity/temperature.

9. Gellvann Digital Thermometer with Magnet and Stander

This entry on our list is a bold one! Why? Thanks to its sharp-black, easy-to-read, and large LCD display. The three bright red buttons also help!

It has a range of -50 to +70 degrees Celsius and can show minimum and maximum temperatures as well. The product is also equipped with a removable probe and with 2 convenient magnets on the back.

In short, you can place the main unit on the fridge door and have the probe measure the temperature inside the freezer or fridge. You can also press the middle red button to switch between indoor and outdoor reading.

10. ORIA Digital Freezer Thermometer, 4.3 Inch with 3 Audible Alarms and 2 Wireless Sensors

If you want the ultimate temperature reading and control unit, then this wireless thermometer is designed for you! Why? Let’s take a good look at it!

The product comes equipped with two remote sensors that can be placed anywhere in your home or your fridge, so the right temperature is set. The main unit – or console – displays the readings from both sensors at the same time, including that of the built-in indoor sensor.

The unit shows, simultaneously, the remaining battery of the 2 wireless sensors, the current temperature, the minimum and maximum, as well as whether an alarm is set or not.

It is, without any doubt, the most comprehensive thermometer on our list.

Best Fridge Freezer Thermometers – Buying Guide

Now, the ten products listed above may not be your cup of tea, so to speak. Perhaps you’re looking for different looks, colours, builds, and so on.

While you’re free to choose any colour imaginable for your fridge thermometer, there are a couple of things that you shouldn’t skip on checking when buying a new thermometer – especially if you’re a first-time buyer.

This is why we’ll now take you through the things you have to take into account when buying a fridge thermometer!

Digital vs. Traditional Refrigerator Thermometers

The main difference between the two is that one needs a battery to function while the other relies only on mercury. Reportedly, both types of thermometers are highly accurate – but there’s more to it!

If you want to check temperatures down to their decimals or, furthermore, have an idea of the minimum and maximum temperatures in your fridge, then you must go for one of the digital fridge thermometers available.

On the other hand, if an easy to read display will satisfy you and you don’t want anything fancy food in your fridge, a thermometer with a reliable dial will do the trick.

Fridge Freezer Thermometer Accuracy

Naturally, the next thing you want to get right when it comes to a thermometer is accuracy. While both digital and traditional thermometers are generally accurate, they may have flaws in their build that make for inaccurate readings.

The best way to check the accuracy of a thermometer is to cross-check the results with the ones of other thermometers.

If you’re buying in a shop, this can be easily done. When you’re ordering online, it would be good to have a thermometer at home that you can use for comparison.


As you may have noticed, fridge thermometers, depending on their design, can be used to measure room and freezer temperatures as well. If that’s something you want your thermometer to do, then keep an eye out for usability.

Moreover, keep in mind that some thermometers have to be kept inside the fridge, while others measure via a probe while the main unit can be placed on the fridge’s door.

Determine whether you want to open the freezer’s/fridge’s door every time you want to check the temperature or simply glance over a neat LCD before you start looking at thermometers.


A thermometer that will live among frozen chicken or vegetables must be resilient enough to endure low temperatures, as well as the casual liquid spill. If we’re talking about a digital thermometer, then keep in mind that there are components and the battery that have to be protected.

As such, a flimsy plastic build for an indoor thermometer is a no-no and equals wasted money. A Stainless-steel sturdy build, on the other hand, makes for a thermometer that can stay in a freezer for months.

Additional Features

Here, we’re taking into account only digital thermometers.

As mentioned above, some digital products can show the minimum and maximum as well – but some can do more.

For example, other devices can measure the humidity level as well, can tell you when the temperature inside the freezer/fridge has reached a certain point, via an alarm, and much more.

This is why, before buying a thermometer, think well at the additional features you want it to have. Maybe you want it to show both internal and external readings at the same time!

FAQ – Frequently Asked Questions

No matter how much research you put into buying a new fridge thermometer, there’s always that one thing that you may not know.

Instead of reading manuals with poor translations and what-not, we’ve prepared this short and highly informational FAQ section for all of your fridge thermometer questions and uncertainties!

Q: When is the best time to check the temperature for a newly purchased thermometer?

Manufacturers and buyers alike recommend you to check the temperature in the morning. This is because the fridge has been sealed shut for the entire night and the temperature inside is at a stable level, ready for reading.

Q: Where should a fridge thermometer be placed?

When trying to find the best place for a thermometer, take into account the fact that fridges and freezers, despite their natural ability to be overall cold, have a warm spot as well. A light bulb, for example, may influence the readings of a thermometer.

Reportedly, the ideal spot for a thermometer or a sensor probe would be near the door, between the coldest and warmest spots.

Q: What fridge/freezer areas can result in inaccurate temperatures?

The back and bottom part of refrigerators and freezers are known to be the coldest parts of a refrigeration unit. You shouldn’t place the thermometer there as you’ll think the fridge is colder than it is.

Q: What’s the first thing to do after buying a new fridge thermometer?

Depending on the type of thermometer, it is recommended to place it inside the fridge or freezer – or its temperature probe -, and let it calibrate for at least 12 hours.

If you do so, the thermometer will get a near-perfect reading and will calibrate itself for future uses.

Q: What are the usual fridge and freezer temperatures?

If you don’t have any special requirements, then the usual for your fridge should be of 4 degrees Celsius and -18 degrees Celsius for your freezer.

However, if you have to change the temperatures via the fridge’s temperature knob, keep in mind that you have to let the thermometer read the new temperature for at least 12-24 hours. A properly calibrated fridge thermometer will always show accurate temperatures!

Final Thoughts

Fridge thermometers are not as simple as they seem. When it comes to body temperatures, we know that the best spot for them is under our tongue. That’s all we have to do to get an accurate reading.

On the other hand, fridge and freezer thermometers need to be placed in specific spots inside the fridge and also calibrated. Moreover, those products that come with several additional features may be even harder to use, especially when there’s more than one sensor involved.

However, if you follow our review and buying guide while choosing your new fridge thermometer, you should have no problems in choosing the best and most accurate product on the market!
