A reliable thermometer isn’t just a nice-to-have at home. It’s a must, especially if you live with kids, seniors, or anyone prone to getting sick. When a fever strikes, you want to get an accurate reading fast so you can decide what to do next. But with so many types of digital thermometers available in the market, it can be tricky to figure out which one works best for your household.
For starters, there are three common types of digital thermometers—forehead, ear, and pencil thermometers—and each has its own strengths and limitations. OMRON, a brand that is recognized globally for its reliable and clinically validated healthcare equipment and solutions, offers all three types of thermometers. While you can be sure that all OMRON digital thermometers are clinically tested and meet international standards, you still need to select the type that best fits your needs. To help you make the best choice, here’s a breakdown of what each type offers and what to consider when shopping.
Forehead Thermometers
Forehead thermometers, sometimes referred to as temporal thermometers, use infrared sensors to scan the temperature of your temporal artery. This artery is located just under the skin of your forehead. All you have to do to use this type of digital thermometer is either hold or swipe the device across the forehead. Give it a few seconds so you can get an accurate reading.
One of the biggest advantages of forehead thermometers is that they’re non-contact. This makes them more hygienic, especially in applications where multiple people may be using the same device. They’re also incredibly convenient if you need to take someone’s temperature while they’re sleeping. With this type of thermometer, you won’t have to wake up a fussy toddler or light sleeper to check if they have a fever. Because of these features, forehead thermometers are a popular choice in homes with infants, and they are often favored for communal health screenings.
However, it’s worth noting that forehead temperature readings can be affected by sweat, skin conditions, or exposure to external temperatures, like being in front of an electric fan. These thermometers also tend to be more expensive than other types. That said, if you value speed and ease of use, this might be the right type of thermometer for you.
Ear Thermometers
Ear thermometers or tympanic thermometers measure the heat emitted from the eardrum using infrared technology. They’re also known for providing fast results, as they can offer accurate temperatures in just a few seconds when positioned correctly in the ear canal.
These thermometers offer a balance of speed and accuracy, and they work best for toddlers, older children, and adults. They’re especially helpful for monitoring fever throughout the day because they provide consistent results when used properly.
Still, there are a few things to watch out for when using ear thermometers. If the person has an ear infection or excess earwax, for example, the reading might be inaccurate. For infants younger than six months, ear thermometers aren’t recommended because their ear canals are still too small. Plus, you need to make sure the probe is inserted at the right angle; otherwise, the results might not be reliable.
Pencil Thermometers
Pencil thermometers are the most traditional type of digital thermometer. They’re shaped like a pen and can be used under the tongue (oral), under the arm (axillary), or rectally. For home use, most people stick to oral or underarm measurements. This type of thermometer is sometimes referred to as a stick or oral thermometer.
The biggest draw of pencil thermometers is their affordability. You’ll find them almost everywhere, from drugstores to supermarkets, and they’re easy on the wallet. They’re also straightforward to use and don’t rely on any fancy technology.
That said, you’ll need to clean pen thermometers thoroughly after every use, especially if they’re shared. And because they require contact, you’ll need some cooperation from the person being checked, which can be tricky with restless kids. Finally, pen thermometers can take around 30 seconds to deliver results. Some models, like OMRON’s Pencil Thermometer MC-343F, are designed to specifically address this issue by providing quick and accurate temperature readings.
What to Consider When Choosing a Thermometer
Now that you know the basics of each type, how do you choose the one that’s right for you? Here are a few things to think about before buying:
1. Age of Users
If you have babies or toddlers at home, non-contact forehead thermometers are often the easiest option. Ear thermometers work well for kids and adults, while pencil thermometers are best for cooperative older children and adults.
2. Purpose of Use
Will you use the thermometer frequently or just occasionally? For regular use, especially during flu season or outbreaks, a fast and hygienic option like a forehead or ear thermometer may be more practical. If it’s just for the occasional temperature checks, a pencil thermometer will do.
3. Hygiene and Convenience
Non-contact thermometers are the most hygienic since they don’t touch the skin. Ear and pencil thermometers need to be cleaned after each use. If you don’t want the hassle of disinfecting, go for a forehead model.
4. Speed and Accuracy
Forehead and ear thermometers offer quick readings, usually within 1 to 3 seconds. Pencil thermometers are slower but can still be accurate if used properly. If you need instant results, such as when monitoring someone closely, models that produce quicker results are worth the investment.
5. Budget
Pencil thermometers are the most budget-friendly. Forehead thermometers are on the higher end, and ear thermometers fall somewhere in the middle. Think about how much you’re willing to spend and balance that with your needs.
6. Features
Some digital thermometers come with added perks like backlit screens, memory recall, fever alerts, or compatibility with health apps. These can be helpful, but they usually come at a higher price.
If you value speed and ease, a forehead thermometer might be the way to go. If you’re after something that balances accuracy and convenience, an ear thermometer could be your match. And if you want something simple and cost-effective, a pencil thermometer has you covered. It also pays to invest in a brand you can trust—like OMRON. The brand has made a name for itself by consistently offering clinically proven, innovative medical equipment. Its thermometers are designed for accuracy, ease of use, and reliability, making them a solid choice for everyday health monitoring. With the right OMRON thermometer on hand, you’ll be better prepared for whatever comes your way.
