Best Overall Thermometer


F-Doc V2X Non-Contact


Temperature Range: Body: 89.6-109.2 F; Object: 32-212 F | Modes: Forehead
REASONS TO BUY
High precision
Fast readings
REASONS TO AVOID
Clunky design
Buttons are difficult to press

The F-Doc V2X Non-Contact is a large, trigger-style infrared thermometer. It was one of the most accurate and precise devices we used throughout our testing. It provides readings almost instantaneously (in about a second) and can take both forehead temperatures and readings of inanimate objects. It automatically turns off after approximately 30 seconds to save battery power and displays 'lo' or 'hi' when forehead readings fall outside of a normal range. Its memory function holds 32 readings and can record both forehead and inanimate object temperatures (most models with a memory function only retain the former).

Our main gripe with this product is the user interface. In addition to the temperature scanning trigger (memory recall, volume, C/F, mode). They are very small, difficult to press, and may be difficult to read for some folks. They also take up valuable real estate, requiring the readout screen to be smaller. Lastly, though you won't have to access it often, the battery compartment latch is hard to open. All in all, this multi-purpose device is an excellent, highly precise option that we would gladly keep on hand in your bathroom's medicine cabinet.

Best Basic Digital Probe Option


Vicks SpeedRead V912US


Temperature Range: 89.6-109.4 F | Modes: Oral/Underarm/Rectal
REASONS TO BUY
Color-coded backlight
Large display
REASONS TO AVOID
Long read time
Low memory capacity

The Vicks SpeedRead V912US is a basic digital probe model that is easy to use and read. It has a single button and a large, bold font screen and displays a green/yellow/red backlight color corresponding to the severity of its temperature reading. Press the power button once to turn it on, and the device displays the previous temperature reading for a couple of seconds while it gets ready to take the next one.

The downsides of this model are minor. Its memory only records one previous temperature reading, and it only displays this for a couple of seconds, and then it's gone. As a traditional probe model, it takes between 5-10 seconds to yield a reading instead of the near-instantaneous output of infrared styles. Still, we love this model and think it's a great option for anyone who needs a basic digital probe thermometer.

Best Simple Infrared Option


iHealth No-Touch Infrared Forehead


Temperature Range: 89.6-109.2 F | Modes: Forehead
REASONS TO BUY
Highly precise
Simple
REASONS TO AVOID
No additional features
Expensive

The iHealth No-Touch Infrared Forehead is a sleek, no-frills infrared contender. Its simple one-button interface is straightforward to use — just one press to turn it on and a second to take a reading, and it shares results almost instantaneously in a large font digital readout. Many models beep to indicate a final reading, but we appreciate that the iHealth vibrates instead. Best of all, it is highly accurate, not only taking the correct temperature but returning the same result repeatedly.

Some folks might like this device's simplicity, but it is also very basic. This model can only take forehead readings despite the infrared technology and futuristic aesthetic. It has no memory or color-coded backlights and does not measure the temperature of inanimate objects. It also tends to be one of the more expensive models. However, if you need a straightforward and highly accurate product, this one is your best bet.

Excellent User Interface


FACEIL Thermometer


Temperature Range: 89.6-108.5 F | Modes: Forehead
REASONS TO BUY
Interface is easy to navigate
Large, bold font
REASONS TO AVOID
Many buttons
Lots of data on screen

The FACEIL Thermometer is a have-it-all-at-once kind of product. If you use it a lot and can get oriented quickly to what you are looking at, we think it is one of the best user interfaces of the bunch. It has a large screen and bold font, which we love. As with all other infrared options, it completes a scan in about a second. Taking a basic reading then displays the current recorded temperature and icons for the mode (human body or object), volume, battery level, and memory readings.

The flip side to having all of the information displayed simultaneously is that some people might find it overwhelming. And though it is relatively user-friendly, we found that it is less accurate than average. It also doesn't come with color-coded backlights. However, if you want the speed and convenience of a forehead scanner and don't mind the way the data is displayed, we would highly recommend this option.

Best Analog Option


Geratherm Mercury Free Oral Glass


Temperature Range: 95.2-108.0 F | Modes: Oral
REASONS TO BUY
Simple to use
No batteries
REASONS TO AVOID
Reading takes a long time
Difficult to read

The Geratherm Mercury Free Oral Glass is a traditional glass model. No batteries, no buttons; the benefit of this product is that it is as simple as it gets. It comes with a calibrated insert that allows you to see both Fahrenheit and Celsius readings simultaneously. It is also highly accurate if the patient can hold it in place properly.

There are a few drawbacks to this model. First, readings take over three minutes, compared to an average of a couple of seconds for all other products in this review. Readings can also be difficult to discern since the glass has to be held at the right angle, and the font is small and thin. It is also not ideal for small children or adults who might have trouble keeping it adequately positioned under the tongue for that long. However, this is the perfect choice for those who prefer a conventional and precise option.

A Good Budget Option


Boncare 10-Second Digital


Temperature Range: 89.6-109.4 F | Modes: Oral/Underarm/Rectal
REASONS TO BUY
Flexible tip
Versatile
REASONS TO AVOID
Small screen
Not instantaneous reading

The Boncare 10-Second Digital is a multi-location digital probe thermometer. It is lightweight, compact, and accurate. You can take readings orally and under the arm or rectally (facilitated by a flexible plastic tip). It might be too subtle if you don't use it often, but the beep frequency changes depending on whether a reading is 'normal' or high. It also stores the previous reading and displays it for a couple of seconds the next time the device is turned on and before a new reading is taken.

We had some gripes regarding the user-friendliness of this product (or lack thereof). The readout screen is small, and some may find it difficult to read. As a traditional probe thermometer, it takes between 10-15 seconds to produce a reading — not a huge issue, but it is notably longer than any infrared scanner. The single power button is somewhat small, and folks with larger fingers or arthritis may find it hard to depress. All told, though, if you just need the basics, this device is of great value.

Best Option with Ear Reading


CHOOSEEN Thermometer


Temperature Range: Body: 89.6-109.2 F; Object: 32-212 F | Modes: Forehead/Ear
REASONS TO BUY
Takes readings in multiple body areas
Ergonomic
REASONS TO AVOID
Inconvenient buttons
Imprecise

The CHOOSEEN Thermometer is a multi-purpose infrared temperature reader. Its color-coded backlights are a helpful visual cue indicating normal, low-grade, and high-fevers, and its screen has a large font for easy reading. It is also versatile, offering the ability to take temperature readings of inanimate objects. Its basic forehead scanning function is easy to use, and we love that it comes with a removable cap that reveals it can be used as an ear probe as well.

However, this device wasn't without frustrations. It features three fairly standard buttons: scan, mode, and memory. The last two are fixed on the underside of the product. Since certain operations require multiple button pressings, we needed to flip over the device often to ensure we were pushing them correctly. Most problematically, this is the least precise model we tested. Although it still provided accurate readings, there was a slight variance of a little less than a degree on multiple occasions (as opposed to some products that were far more consistent).

A Good Option for Versatility


GoodBaby Touchless


Temperature Range: Body: 89.6-109.2 F; Object: 32-212 F | Modes: Forehead
REASONS TO BUY
Fast
Inanimate object readings
REASONS TO AVOID
Some buttons are not intuitive

The GoodBaby Touchless is a fast and reliable infrared forehead scanner. During testing, it consistently provided readings within a few tenths of a degree of one another. It can also take the temperature of inanimate objects, which significantly increases its versatility. It has a large readout screen and a big 'scan' button, both of which make it easier to use. It holds 35 previous readings in its memory and displays a color-coded backlight that corresponds to the severity of the temperature (normal, low-grade, high).

Though the three buttons each have clearly labeled use (scan, memory recall, and mute/unmute), a couple of other functions like a Fahrenheit/Celcius and mode toggles are less intuitive to access. On the whole, though, we think that this device is easy to use and accurate.

A Reliable Choice with a Handful of Minor Issues


GoodBaby Thermometer


Temperature Range: Body: 89.6-109.2 F; Object: 32-212 F | Modes: Forehead/Ear
REASONS TO BUY
Temperature indicator lights
Auto-off battery saver
REASONS TO AVOID
Ear probe cap is slippery
Memory function doesn't record object readings

The GoodBaby Thermometer is a two-button model with a fair amount of versatility. It has a memory for 35 forehead readings and a color-coded indicator light to tell you when it takes a normal or high reading. The backlit display makes it relatively easy to read, and it beeps as it displays the recorded temperature. This infrared scanner can take readings from the forehead or the ear.

Although minor, the problems we encountered with this model add up. We appreciate the temperature indicator light but preferred models that incorporate the colors into the backlight of the main display rather than making it a separate part of the device. Additionally, the quality feels like it is on the cheaper side of the spectrum. The buttons make a deep cuh-chunking sound, and we think the print will eventually rub off. The ear probe cover lacks grip tabs, making it very slippery and challenging to pull off. Despite these drawbacks, this thermometer is still a versatile tool to have at your family's disposal.

Why You Should Trust Us


Lead reviewer Ben Applebaum-Bauch has been with GearLab for almost four years. In that time, he has tested over 200 individual home goods and consumer electronics products and researched hundreds of others, from electric razors to toothbrush heads, facial tissues, and candles. Thermometers are a critical part of your home personal care toolkit; as a former wilderness first responder, Ben is no stranger to the necessity for speedy and accurate information.

At GearLab, we purchase each product we test at retail prices and do not accept any manufacturer samples. Besides testing and comparing accuracy, we also considered ease of use from out of the box to operating, recorded how long it takes for each device to register a reading, and noted any additional features that improve the performance of a product.

Our testing of thermometers is divided across four rating metrics:
  • Accuracy
  • Ease of Use
  • Features
  • Speed

We subjected the competition to more than four tests, totaling over 40 tests. Scores in these test metrics combine and make up a product's overall score.


Analysis and Test Results


We created a test plan with a few different test metrics to test all aspects of a product's performance. For each metric, we highlight the contenders that outperform or fell short among the competition of thermometers.

Accuracy


Accuracy is the degree to which any given reading by a product represents someone's true temperature. That is, if you have a fever of 100.5 degrees Fahrenheit, you want confidence that your thermometer will tell you that your temperature is 100.5 degrees. We prioritized accuracy as the most important metric for a thermometer. During testing, all of the models performed very well. When used as directed, we would gladly rely on any of them to tell us whether or not we had a fever.

This review's three highest performing models were the F-Dox V2X Non-Contact, iHealth No-Touch Infrared Forehead, and Goodbaby Touchless. The first two were accurate and also had zero variance from reading to reading (while the Goodbaby had a couple that varied by a tenth of a degree).

The next tier includes models like the Vicks SpeedRead V912US, Boncare 10-Second Digital, and Geratherm Mercury-Free Oral Glass. These models were also highly accurate with a reading-to-reading variance of a couple of tenths of a degree (about 2-4x more than the Goodbaby Touchless).

The least accurate models were the FACEIL, GoodBaby, and CHOOSEEN. To be clear, they all provided readings that were perfectly acceptable in terms of assessing a fever, but their variance was 10-20x greater than the most precise models.

Ease of Use


Ease of use is how simple it is for a user to get a reading. When you or a family member are feeling under the weather, you don't want to navigate an overly complicated set of buttons. Here, we want to know how intuitive each model is to use.

Unsurprisingly, we found that models with fewer buttons (and fewer functions per button) were, on the whole, easier to use. This put digital probe options like the Vicks SpeedRead V912US and Boncare 10-Second Digital toward the top. They both just have a single button and take a straightforward body temperature reading. For the traditionalists, the Geratherm Mercury-Free Oral Glass is a regular old analog thermometer (obviously, zero buttons). This one is straightforward to use but much less easy to read due to the small type size and having to angle the product correctly.

As for digital products, the iHealth No Touch Infrared Forehead also has just one button. The GoodBaby Touchless has three buttons (temperature, memory recall, and mute/unmute) that more or less do what you would expect them to and are thus straightforward enough for someone to use intuitively, without instruction.

In terms of button configuration, we are decidedly not fans of the F-Dox V2X Non-Contact, which has more buttons than it needs to. They also don't work that well, and the functions are not always intuitive. The CHOOSEEN is somewhat sleek looking but puts two of its three buttons on the underside, making it more difficult to use.

Features


Thermometers have one primary task, but additional features can improve the user experience and offer insight beyond a basic temperature reading. We don't just look at the total number of features but assess the value that each one brings.

Several contenders we tested, like the F-Doc V2X Non-Contact, CHOOSEEN, Vicks SpeedRead V912US, and GoodBaby Touchless, have backlight colors that correspond to the seriousness of a temperature reading. For instance, green corresponds to an average body temperature, yellow/orange for a low-grade fever, and red for a high fever. This feature helps make sense of the readings in even less time.

We also appreciate large displays that don't require squinting for most folks. Top performers here include the FACEIL and GoodBaby Touchless infrared devices, as well as the digital probe Vicks SpeedRead V912US. In addition, all of the infrared models in our lineup have some memory storage capacity (except for the iHealth), making it easy to track temperature changes throughout an illness.

Speed


Most of the thermometers we tested offer a relatively rapid response, but the speed at which they produce a reading is also a factor you may want to consider. For this test metric, we timed how long it takes for a product to record a temperature and then compared the results.

All of the digital thermometers have some auto-off function. In practice, we discovered that the most user-friendly ones keep the reading up for about 15 seconds.

During testing, three distinct speed tiers emerged that correspond to the type of each thermometer. Infrared forehead/ear scanners are all almost instantaneous. They take about one second to record and report a reading. Digital probe options, like the Vicks SpeedRead V912US and Boncare 10-Second Digital, fall into the middle tier with a range of time-to-reading times between 9-13 seconds. Lastly, the analog Geratherm Mercury-Free Oral Glass took far and away the most prolonged amount of time, recording reading speeds of 2.5-4 minutes.
