9 Best Thermometers for Adults in the UK 2024

Our number one pick has almost everything you could want from a thermometer, such as age precision technology, which can be adjusted to the user (as what constitutes a high temperature depends on age). It also has a flexible tip and backlit LCD display which changes colour to indicate whether there is a fever. 

Braun are a premium German brand that are recognised for their high-class engineering, and here they certainly deliver. This product has 4.7 out of 5 stars on Argos, with many reviewers saying that they love the quality and the reliability. For these reasons, this thermometer takes our top spot! 

Using a thermometer can feel pretty invasive, even at the best of times, which is why we love this no-touch offering from Braun. It can capture an accurate reading from 2 cm away so you won't have to poke or prod your partner or relative when they're not feeling well or having a nap. 

Also, to make sure they don't wake up, you have the option of putting this gadget on silent mode, so there will be no startling buzz. The readings are available in around 2 seconds, and can be displayed in either °C or °F.

Know that you want to go with infrared readings, but don't know whether you want in-ear or forehead? Why not have both! That's what this thermometer from HR allows, which can reassure you of complete accuracy after comparing two different measurements.

It also has not one but three green, orange and red fever indicators, so you'll never be unsure as to what your reading means or when it's time to call the Doc. This is a truly trusty companion to be welcomed into any adult home.

This digital sick thermometer comes with a flexible tip, which is generally considered much comfier and easier to clean by users. It also has fever indicator capabilities, showing an 'L' for low temperatures and an 'H' for high, as well as being very lightweight.

Furthermore, this device has a couple of other nifty additional features that one may wish for when choosing a thermometer, such as auto shutoff, and a memory that can show you your last reading. Not bad for around £10!

Braun are the leading thermometer manufacturers in the UK, and we're going to be getting a little more acquainted with them the deeper we get into this article. First up is the Thermoscan 7, which not only has great accuracy but also an in-ear guidance, so you know you're definitely measuring in the right spot. 

Plus, it has a large, backlit LCD display that's simple to read and simple to navigate. This option also comes with a storage case, 21 single-use covers and 2 AA batteries, the latter two of which are both easily replaced. 

As the name suggests, this thermometer provides clinical accuracy when it comes to reading temperatures. The appliance will signify when your reading is done by emitting a little bleep, which means you don't have to wait around or risk forgetting. 

This product can be used on people of any age and is CE certified, which just means it conforms with certain health, safety and environmental standards. Take note that you'll need to also order in some of its specific LR41 batteries, as there isn't always one included. 

Owing to its compact size, this 4-in-1 thermometer can take readings on different body areas as well as objects and room temperatures. Furthermore, it has an intuitive fever indication and a child mode, making it a good pick for adult households who have a few kids running around, too. 

It'll also save your last 20 readings, power off after 10 seconds, and can switch to a silent mode for minimal disturbance whilst your patient is sleeping off the illness. It's a little pricey, but worth the investment, we think. And batteries are included, after all! 

This easy-to-use ear thermometer will help identify body temperature and alert you of a fever by displaying 'H', so you'll know if you should be worried or not. It has an incredibly fast reading time of 1 second and is capable of storing up to 10 measurements.

Within the box you'll also get 20 single-use covers for the probe to get you started. Unfortunately, it does have a rather small screen that doesn't come with a backlight, so it could be difficult to see clearly in the dark. 

Our cheapest buy on the list is this offering from Yivans. Seeing as it has a rigid tip, it would be best used in the mouth or underarm as the other option could be rather uncomfortable. This thermometer works in around 1 minute, and has an accuracy of around 0.1°.

However, some reviewers have noted that their packages arrived without the instructions, which is not ideal, particularly when using a device that could save lives. Also, it may be difficult to pick up the readings if your sight isn't too sharp, due to the size of the display.
